Procedure

A solution of the amine (A) (0.1 g, 0.35 mmole) and 1,1'-carbonyldiimidazole (0.056 g, 0.35 mmole) in tetrahydrofuran (5 ml) was stirred at room temperature for five hours. The solvent was then evaporated and the residue was dissolved in ethyl acetate (20 ml). This solution was washed three times with water (300 ml, total), dried (MgSO4), evaporated and the residue triturated with a mixture of 60°-80° C. petrol:ether to give, as a white solid, the title compound, 0.074 g (68%), m.p. 223° C.
