Participants

Reaction Steps

A solution of 6-fluoro-2,3,4,5-tetrahydro-1,4-benzothiazepine (2.04 g, prepared in a similar manner to its hydrochloride, Example 3 above) in acetic anhydride (22 ml) was stirred at room temperature for one hour. The reaction mixture was poured into ice and extracted with dichloromethane. The organic layer was dried and the solvent removed by evaporation. Purification of the residue by flash chromatography using dichloromethane/ethanol (97:3) as eluent gave 4-acetyl-6-fluoro-2,3,4,5-tetrahydro-1,4-benzothiazepine as an oil. Yield 1.7 g.
