Procedure
3-Chloro-2,5-dihydro-1,4-benzothiazepine (5 g) and a 33% solution of methylamine in absolute ethanol (150 ml) were heated under reflux for one hour. The mixture was cooled and filtered. Purification of the residue by flash chromatography using ethyl acetate/ethanol (1:1) as eluent gave 3-methylimino-2,3,4,5-tetrahydro-1,4-benzothiazepine, which was recrystallised from ethanol. Yield 0.51 g (m.p. 278°-280° C.).
