Procedure

1.86 g of (+)-cis-2-(4-methoxyphenyl)-3-hydroxy-5-[2-(dimethylamino)ethyl]-2,3-dihydro-1,5-benzothiazepin-4(5H)-one and 1 ml of triethylamine are dissolved in 15 ml of methylene chloride, and 1.27 g of 5-chloro-2-nitrobenzoyl chloride are added thereto. The mixture is stirred at room temperature for one hour. After the reaction, the mixture is poured into ice-water and then extracted with ethyl acetate. The extract is washed with an aqueous sodium bicarbonate solution, water and an aqueous sodium chloride solution, successively. Then, the extract is evaporated to remove solvent, and the residue is crystallized with ethanol. 2.45 g of (+)-cis-2-(4-methoxyphenyl)-3-(5-chloro-2-nitrobenzoyloxy)-5-[2-(dimethylamino)ethyl]-2,3-dihydro-1,5-benzothiazepin-4(5H)-one are thereby obtained as colorless prisms. Yield: 88.1%.
