Reaction Steps

A mixture of 4-(diphenylmethoxymethyl)-1-(4-nitrophenethyl)piperidine (1.40 g, 3.3 mmol) (see Example 13) and stannous (II) dichloride dihydrate (3.68 g, 16.3 mmol) in ethanol (20 ml) was heated at 70° C. for 2 hours, allowed to cool to room temperature and filtered. The filtrate was evaporated and the residue partitioned between ethyl acetate and saturated aqueous sodium hydrogen carbonate solution. The layers were separated and the aqueous layer extracted into ethyl acetate. The combined organic layers were washed with saturated brine, dried over magnesium sulphate and evaporated. The residue was triturated with ether and the resulting solid collected, washed with ether and dried to give the title compound (0.66 g) as a fawn solid, m.p. 188°-190° C., which was characterized by its 1H-NMR spectrum.
