Abstract

A process for preparing hydrochloride of 3-acetoxy-2, 3-dihydro-5-[ 2-(dimethylamino)ethyl]-2-(p-methoxyphenyl)- 1, 5-benzothiazepin-4(5H)-one which comprises reacting 3-hydroxy-2, 3-dihydro-5-[2-(dimethyl-amino)ethyl]-2-(p-methoxyphenyl)-1, 5-benzothiazepin-4(5H)-one with acetyl chloride in acetic acid or a mixed solvent of acetic acid and acetic anhydride. According to the process, hydrochloride of 3-acetoxy-2, 3-dihydro-5-[2-(dimethylamino)ethyl]-2-(p-methoxyphenyl)-1,5-benzo-thiazepin-4(5H)-one is readily obtained in one step.
