Procedure

9 ml of 33% hydrobromic acid in acetic acid are added dropwise to a solution, cooled to approximately 0° C., of 1.8 g (5.42 mmol) of phenylmethyl 2-(6-phenylpyrid-3-yl)ethylcarbamate, prepared in stage 1.1., in 50 ml of dichloromethane. Stirring is continued at ambient temperature for 2 hours. The mixture is concentrated under reduced pressure and the residue is taken up in dichloromethane and a saturated aqueous sodium hydrogencarbonate solution. The aqueous phase is separated and is extracted twice with ethyl acetate. The combined organic phases are washed with a saturated aqueous sodium chloride solution and dried over sodium sulphate, and the filtrate is concentrated under reduced pressure.
