Ammonia → HCID 67931168, compound

Participants

Reaction Steps

In 220 ml of methanol is dissolved 6.9 g of ethyl cis-3-amino-8-chloro-4-oxo-2-phenyl-2,3,4,5-tetrahydro-1,5-benzothiazepine-5-acetate, into which ammonia gas is blown to the level of saturation under ice-cooling. The reaction temperature is slowly elevated to room temperature, and the mixture is allowed to stand still overnight. Then, the reaction mixture is concentrated under reduced pressure. The separated crystals are collected by filtration to give 6.2 g of cis-3-amino-8-chloro-4-oxo-2-phenyl-2,3,4,5-tetrahydro-1,5-benzothiazepine-5-acetamide.
