Reaction Steps

The product of step (a) (0.39 g) was dissolved in toluene (10 ml), triethylamine (0.26 ml) and thionyl chloride (0.13 ml) were added and the mixture stirred at room temperature for 20 hours. The solvent was removed by evaporation, a solution of 4,4-diphenylpiperidine hydrochloride (0.478 g) in dimethylsulphoxide (10 ml) and triethylamine (0.65 ml) added. After 2 hours water and ethyl acetate were added, the organic phase was separated, washed with brine, dried and the solvent removed to leave a gum. Purification by supercritical fluid chromatography gave a solid which was treated with 1.0M ethereal hydrogen chloride solution to give the product as a solid (0.02 g), m.p. 254-255° C.
