실험 절차

Under a nitrogen blanket, a 2.0 g sample of dl-cis-2-(4-methoxyphenyl)-2,3-dihydro-3-hydroxy-1,5-benzothiazepin-4(5H)-one (6.8 mmol) was refluxed neat with 20 mL of thionyl chloride (27.6 mmol) for approximately 2 hours. Then, 50 mL of hexane and about 20 mL of ether were added, and solid product was filtered off. The solid was dried under vacuum to obtain 1.4 g of 2-(4-methoxyphenyl)-3-chloro-1,5-benzothiazepin-4(5H)-one (66 percent yield of theory).
