Procedure

The solution of 0.650 g of tert-butyl 4-[4-(3-cyanopropoxy)phenyl]-3-[1-(3-methoxypropyl)-2-oxo-1,2,3,4-tetrahydroquinolin-7-ylmethoxy]piperidine-1-carboxylate in 10 ml of ammonia (2M in methanol) is hydrogenated in the presence of 0.65 g of Raney nickel at 45° C. over 3 hours. The reaction mixture is clarified by filtration and the filtrate is concentrated by evaporation. The title compound is obtained as a brown oil from the residue by means of flash chromatography (SiO2 60F). Rf=0.13 (200:20:1 dichloromethane-methanol-conc. ammonia); Rt=4.18.
