Reaction Steps

A solution of the 4-(4-nitrophenyl) piperidine (29.3 g, 0.144 mol) obtained in (i) in ethyl acetate (150 ml) was hydrogenated at 3 atmospheres over Raney Nickel (5 g) until uptake of hydrogen ceased. Evaporation afforded a brown oil which was crystallised from ether to give the desired product as light yellow crystals (18.5 g, 74% yield), M.pt. 85°-87° C.
