Potassium Carbonate → HCID 11004065, compound

Participants

Reaction Steps

A mixture of 6.4 g of (-)-cis-2-(4-methoxyphenyl)-3-hydroxy-8-chloro-2,3-dihydro-1,5-benzothiazepin-4(5H)-one, 3.0 g of 2-(dimethylamino)ethyl chloride hydrochloride, 5.8 g of potassium carbonate and 150 ml of acetone is treated in the same manner as described in Example 1. The crude product thus obtained as recrystallized from a mixture of ethyl acetate and n-hexane. 6.93 g of (-)-cis-2-(4-methoxyphenyl)-3-hydroxy-5-[2-(dimethylamino)ethyl]-8-chloro-2,3-dihydro-1,5-benzothiazepin-4(5H)-one are thereby obtained as colorless needles.
