Reaction Steps

A mixture of 1.6 g of (±)-cis-2-(4-methylphenyl)-3-hydroxy-5-[2-(N-benzyloxycarbonyl-N-methylamino)ethyl]-8-methyl-2,3-dihydro-1,5-benzothiazepin-4(5H)-one, 0.69 g of benzoyl chloride, 5 ml of pyridine and 2 ml of benzene is stirred at room temperature for 2 hours. The mixture is poured into ice-water, and the aqueous mixture is extracted with ethyl acetate. The extract is washed with water, dried and then evaporated under reduced pressure to remove solvent. 2.14 g of (±)-cis-2-(4-methylphenyl)-3-benzoyloxy-5-[2-(N-benzyloxycarbonyl-N-methylamino)ethyl]-8-methyl-2,3-dihydro-1,5-benzothiazepin-4(5H)-one are obtained as an oil.
