実験手順

10.7 g of (-)-cis-2-(4-methoxyphenyl)-3-hydroxy-5-[2-(N-benzyl-N-methylamino)ethyl]-8-methyl-2,3-dihydro-1,5-benzothiazepin-4(5H)-one perchlorate is converted to its free base, and 80 ml of acetic anhydride and one ml of pyridine are added thereto. The mixture is heated at 100° C. for 4 hours. The mixture is evaporated under reduced pressure to remove acetic anhydride and pyridine. Benzene is added to the residue, and the mixture is evaporated under reduced pressure to remove solvent. 10.37 g of (-)-cis-2-(4-methoxyphenyl)-3-acetoxy-5-[2-(N-benzyl-N-methylamino)ethyl]-8-methyl- 2,3-dihydro-1,5-benzothiazepin-4(5H)-one are obtained as an oil.
