Procedure

1.52 g of (+)-cis-2-(4-methoxyphenyl)-3-acetoxy-5-[2-(N-benzyl-N-methylamino)ethyl]-8-chloro-2,3-dihydro-1,5-benzothiazepin-4(5H)-one, 1.24 g of benzyloxycarbonyl chloride and 18 ml of benzene are treated in the same manner as described in Example 4-(2), whereby 1.64 g of (+)-cis-2-(4-methoxyphenyl)-3-acetoxy-5-[2-(N-benzyloxycarbonyl-N-methylamino)ethyl]-8-chloro-2,3-dihydro-1,5-benzothiazepin-4(5H)-one are obtained as an oil.
