A multistep process for producing 8-chloro-6-(2-fluorophenyl)-1-methyl-4-H-imidazo[1,5a][1,4] benzodiazepine (midazolam) comprises treating a compound of Formula II with a lower alkyl dithiol to produce a compound of Formula III, wherein n = 2 or 3, converting the compound of Formula III to a compound of Formula VII, and then treating the compound of Formula VII with a deprotecting agent, thereby producing midazolam. Novel intermediate compounds are also disclosed.
一种生产 8-氯-6-(2-氟苯基)-1-甲基-4-H-咪唑并[1,5a][1,4]苯并二氮杂卓(咪达唑仑)的多步骤工艺包括用低级烷基二硫醇处理式 II 的化合物,生成式 III 的化合物(其中 n = 2 或 3),将式 III 的化合物转化为式 VII 的化合物,然后用脱保护剂处理式 VII 的化合物,从而生产咪达唑仑。还公开了新型中间体化合物。
