Abstract
Description
ダビガトラン エテキシラートは、本分野において公知であり、国際特許出願WO 98/37075で最初に開示された。ダビガトラン エテキシラートの製造方法も、WO 2006/000353又はHauelらの文献(J. Med. Chem, 2002, 45, 1757 ff) から公知である。
Hauelらの文献に従うと、式(1)の化合物は、Pd/Cを用いる水素化によって、式(2)のニトロ化合物から得られうる。
驚いたことに、発明の根底にある問題は、この反応混合物に第三級アミンを添加することで、解決されうることが分かった。
その結果として、本発明は、式(2)の化合物の接触水素化による、式(1)の化合物の合成に関し、反応を第三級アミンの存在下で実施することを特徴とする。
また、水素化が0.5バール〜25バールの圧力下で、好ましくは1バール〜8バールの圧力下で、特に約2〜6バールの圧力下で行われる、方法が好ましい。
不活性雰囲気(N2)下で、オートクレーブを150gの化合物(2)、6gの10%パラジウム担持炭触媒、7 mlのトリエチルアミン及び630mlの酢酸エチルでチャージした。オートクレーブを30℃に加熱し、4バールの圧力になるまで水素を加えた。次いで、温度を50℃に調整した。出発材料の完全な変換のための通常の時間は、1〜2時間だった。次いで、オートクレーブを冷却させて、懸濁液をろ過して触媒を除いた。有機ろ液を、ロータリーエバポレーターで濃縮して、350mlのイソプロパノールかトルエンで希釈した。再びこの溶液を穏やかに真空濃縮し、400mlのイソプロパノールかトルエンを添加した。該溶液を10℃に冷却し、生成物を結晶化させた。この粗生成物をろ過で分離し、真空乾燥させて、123gの式(1)の化合物(90%の理論的収量)を得た。
不活性雰囲気(N2)下で、オートクレーブを150gの化合物(2)、6gの10%パラジウム担持炭触媒及び630mlの酢酸エチルでチャージした。オートクレーブを30℃に加熱し、4バールの圧力になるまで水素を加えた。次いで、温度を50℃に調整した。水素の消費が停止するか、緩やかになったら、オートクレーブを窒素で置換し(flush with)、更に触媒を添加し(およそ開始時の量の50%)、次いで新しく水素を加え、水素化を続けた。出発材料の完全な変換のための通常の時間は、およそ4時間だった。次いで、オートクレーブを冷却させて、懸濁液をろ過して触媒を除いた。有機ろ液を、ロータリーエバポレーターで濃縮して、350mlのイソプロパノールかトルエンで希釈した。再び溶液を穏やかに真空濃縮し、400mlのイソプロパノールかトルエンを添加した。該溶液を10℃に冷却し、生成物を結晶化させた。この粗生成物をろ過で分離し、真空乾燥させて、116gの式(1)の化合物(85%の理論的収量)を得た。
