Procedure
A solution of the amine (A) (1 g, 3.48 mmole) and 1,1'-thiocarbonyldiimidazole (0.62 g, 3.48 mmole) in tetrahydrofuran (20 ml) was stirred at room temperature for one hour. The solvent was then evaporated and the residue was chromatographed on silica (230-400 mesh), eluting with ethyl acetate. One recrystallization from ethanol gave the pure title compound, 0.65 g (57%), as a white solid, m.p. 232°-235° C.
