500L反応缶1の後処理は以下のように実施した。攪拌を開始して水(52kg,2w/w)を加えた後、内温0~25℃で約8%水酸化ナトリウム水溶液(48%水酸化ナトリウム水溶液(11.3kg,水酸化ナトリウムとして135.6mol,1.0M/M)と水(56.5kg,2.17w/w)の混液)を少しずつ滴下し、下層のpHを7.00~8.50(実測値:pH7.84)に調整した。この時、約8%水酸化ナトリウム水溶液は35.55kg使用した。続いて、内温を15~30℃に調整し、30分以上攪拌後、終夜静置した。翌日、pHがpH7.59であることを再度確認した後、上層と下層をそれぞれ分取し、下層のみを500L反応缶1に戻した後、酢酸エチル(82kg,3.15w/w)を加えた。内温15~30℃で5分攪拌後、30分以上静置し、下層(pH7.55)を除去した。缶に残した上層に分取しておいた上層および5%食塩水(食塩(3.3kg,0.13w/w)と水(618kg,2.38w/w)の混液)を加え、内温15~30℃で5分攪拌後、30分以上静置して下層(pH8.23)を除去した。さらに、水(65kg,2.5w/w)を加えて、内温15~30℃で5分攪拌後、終夜静置して下層(pH7.04)を除去した。
500L反応缶2の後処理は、500L反応缶1の操作と並行して同じ作業を実施した。
次に、500L反応缶2の上層を500L反応缶1に移送し、温水45~55℃、減圧度-0.070~-0.085MPaで内容液が約200Lとなるまで減圧濃縮した。ここに酢酸エチル(141kg,5.42w/w)を加えて、再び同条件で減圧濃縮した。この操作をさらに2回繰り返した後、4度目の酢酸エチル(141kg,5.42w/w)を添加する前後でのHPLC分析により内容液の3-[3-(クロロメチル)イソキサゾール-5-イル]ピリジン-2-アミン含量を確認し、内溶液中の3-[3-(クロロメチル)イソキサゾール-5-イル]ピリジン-2-アミン含有量(23.35kg,111.4mol)とその収率(81.9%)を算出した。続いて、もう一度同じ条件で3-[3-(クロロメチル)イソキサゾール-5-イル]ピリジン-2-アミン含量が10.0~13.0%になるまで減圧濃縮を行い、3-[3-(クロロメチル)イソキサゾール-5-イル]ピリジン-2-アミンの酢酸エチル溶液を得た。
窒素気流下,500L反応缶1内の3-[3-(クロロメチル)イソキサゾール-5-イル]ピリジン-2-アミンの酢酸エチル溶液(前工程で得た全量,23.35kg(111.4mol)を含有)を攪拌し、内温15~25℃でジ-tert-ブチルジカーボネイト(53.47kg,245.0mol,2.2M/M)を加え、酢酸エチル(2kg)で洗い込んだ。ここに、あらかじめ調製した4-ジメチルアミノピリジンの酢酸エチル溶液(4-ジメチルアミノピリジン(0.409kg,3.35mol,0.03M/M)と酢酸エチル(8kg)の混液)を加え、酢酸エチル(1kg)で洗い込んだ後、内温10~30℃で22時間以上攪拌した。HPLC分析により反応の終了を確認した後、1,3-ジメチル-2-イミダゾリジノン(50kg,2.12w/w)を加えた。45~55℃の温水循環下、減圧度-0.092MPa以上かつ液留出が弱まるまで減圧濃縮し、GC分析により酢酸エチル含量が7.0%であることを確認後、内温30℃以下まで冷却し、終夜静置した。翌日、濃縮残渣にメタノール(111kg,4.74w/w)を加えて10分以上攪拌し、固体が析出していないことを確認後、溶液を2分割した。次に2分割した溶液を500L反応缶1及び2にそれぞれ加え、それぞれメタノール(各9kg,各0.4w/w)で洗い込んだ。この際、2分割する前の溶液(225.65kg)をHPLC分析した結果、目的のジ-tert-ブチル {3-[3-(クロロメチル)イソキサゾール-5-イル]ピリジン-2-イル}イミドジカーボネート含量は19.37%、含まれているジ-tert-ブチル {3-[3-(クロロメチル)イソキサゾール-5-イル]ピリジン-2-イル}イミドジカーボネート重量は43.71kg(106.6mol,収率:95.7%)であった。
500L反応缶1について、以下のように処理した。攪拌を開始後、内温35~45℃で水(35kg,1.5w/w)を30分以上かけて滴下し、内温35~40℃でジ-tert-ブチル {3-[3-(クロロメチル)イソキサゾール-5-イル]ピリジン-2-イル}イミドジカーボネート(0.010kg)を加えた。内温35~40℃で30分以上攪拌後、固体の析出を確認し、さらに同温度範囲で1時間以上攪拌した。続いて、内温35~45℃で水(35kgを3回,各1.5w/w)をそれぞれ30分以上かけて滴下した後、3時間以上かけて内温5~15℃まで冷却し、同温度範囲で12時間以上攪拌した。遠心分離機で2回に分けて固液分離し、含水メタノール(メタノール(1回につき7kg,0.3w/w)と水(1回につき27kg,1.14w/w)の混液)で洗浄した。洗浄終了後、30分以上遠心分離を行い、標記化合物のwet固体(25.80kg)を得た。このwet固体を混合型真空乾燥機に投入し、外温45~55℃で24時間以上真空乾燥し、標記化合物(21.09kg)を淡黄色固体として得た。
500L反応缶2について、上記と並行して同じ操作を行い、標記化合物(21.22kg)を淡黄色固体として得た。

親化合物である参考例1に記載の3-(3-(4-(ピリジン-2-イルオキシメチル)-ベンジル)-イソキサゾール-5-イル)-ピリジン-2-イルアミンと実施例1ないし3の化合物を、25℃において、Britton-Robinson緩衝液(イオン強度0.3)への溶解度と溶液中安定性を比較した。表1はその結果を示す。
1.実施例1の化合物のマウスにおける薬物動態評価
(1).投与液の調製
実施例1の化合物は、10mM塩酸溶液(和光純薬工業)を含む5%グルコース(大塚製薬)にて0.3mg/mLに溶解し、親化合物である活性体は3mM塩酸溶液(和光純薬工業)を含む5%グルコース(大塚製薬)にて0.3mg/mLに溶解した。
5週齢の雌性ICR系マウス(日本チャールス・リバー)を使用し、実施例1の化合物は2匹を1群とし、活性体は3匹を1群とし、実施例1の化合物及び活性体を3mg/kgの投与量で尾静脈内へ投与した。実施例1の化合物は投与後30分、1、3、5、8時間に、活性体は投与後5分、15分、30分、1、2、4、6、8時間に尾静脈に穿刺し出血させ、ヘパリン処理したピペットで血液を採取した.採取した血液はサンプリングチューブに入れ氷冷下保存後、4℃、10,500xgで5分間遠心分離した。得られた血漿を正確に10μL採取し、分析時まで-20℃で保存した。
実施例1の化合物及び活性体の血漿中濃度は液体クロマトグラフ質量分析計(LC-MS/MS:Waters, Quattro Ultima Pt)を用いて測定し、内部標準法にて定量した。イミプラミン塩酸塩(SIGMA)を、濃度が0.1μmol/Lになるようにアセトニトリル及びメタノール(1:1)混合溶液に溶解し、内部標準物質溶液(IS溶液)を調製した。血漿を融解後、氷上で冷却したままIS溶液を100μL加えて混合し、4℃、7800xgで10分間遠心分離(除蛋白)した後、上清をメンブレンフィルター(Millipore: MultiScreenTM)にて遠心ろ過し、濾液をLC-MS/MS(Waters:Quattro Ultima Pt)にて分析した。得られたクロマトグラムにおいて、実施例1の化合物、活性体化合物(実施例1化合物の親化合物)及び内部標準物質に対応するピークの面積を、解析ソフトウェア(Waters:MassLynx 4.0)で解析し、内部標準法にて、血漿中に含まれる化合物の濃度を算出した。実施例1の化合物を投与した後の活性体濃度は、分子量比、すなわち(実施例1の化合物分子量)/(活性体分子量)の値で補正した。
(1).投与液の調製
実施例2及び3の化合物は、10mM塩酸溶液(和光純薬工業)を含む5%グルコース(大塚製薬)にてそれぞれ1、1.5mg/mLに溶解し、活性体は10mM塩酸溶液(和光純薬工業)を含む5%グルコース(大塚製薬)にて0.5mg/mLに溶解した。
7週齢の雌性ICR系マウス(日本チャールス・リバー)を使用し、2匹を1群として、本発明化合物及び活性体をそれぞれ活性体当量換算して3mg/kgの投与量で尾静脈内へ投与した。投与後20分、45分、1.5、3、5、8時間に尾静脈に穿刺し出血させ、ヘパリン処理したピペットで血液を採取した。採取した血液はサンプリングチューブに入れ氷冷下保存後、4℃、10,500xgで5分間遠心分離した。得られた血漿を正確に5μL採取し、分析時まで-20℃で保存した。
実施例2、3の化合物及び活性体の血漿中濃度は液体クロマトグラフ質量分析計(LC-MS:Waters;ZQ mass detector)を用いて測定し、内部標準法にて定量した。イミプラミン塩酸塩(SIGMA)を、濃度が1μmol/Lになるようにアセトニトリルとメタノールとの混合溶液(9:1)に溶解し、内部標準物質溶液(IS溶液)を調製した。血漿を融解後、氷上で冷却したままIS溶液を50μL加えて混合し、4℃、1607xgで10分間遠心分離(除蛋白)し、上清をLC-MS(Waters:ZQ mass detector)にて分析した。得られたクロマトグラムにおいて、実施例2、3の化合物、活性体化合物及び内部標準物質に対応するピークの面積を、解析ソフトウェア(Waters:MassLynx 4.0)で解析し、内部標準法にて、血漿中に含まれる化合物の濃度を算出した。
