Participants

Reaction Steps

A mixture of (+)-cis-2-(4-methoxyphenyl)-3-(ethoxycarbonylmethyl)oxy-5-[2-(methylamino)ethyl]-2,3-dihydro-1,5-benzothiazepin-4(5H)-one (1.0 g), triethylamine (375 mg), cinnamyl bromide (730 mg) and methylene chloride (20 ml) is stirred at room temperature overnight. The reaction mixture is concentrated under reduced pressure, and the resulting residue is purified by silica gel column chromatography (eluent; chloroform: ethanol=20:1) to give (+)-cis-2-(4-methoxyphenyl)-3(ethoxycarbonylmethyl)oxy-5-[2-(N-methyl-N-cinnamylamino)ethyl]-2,3-dihydro-1,5-benzothiazepin-4(5H)-one as oil product.
