Procedure

To a solution of N-formyl-l-(3-nitrophenyl)-2-phenyl-2-propylamine (5.0g, 0.017mol) in methanol (200ml) was added 10% Pd/C catalyst (0.5g) and the mixture hydrogenated at 50 psi in a Parr apparatus for 3 hours. The catalyst was removed by filtration and the solvent evaporated to a white solid, 4.6g. This solid was recrystallised from isopropanol (50 ml) to give 2.6 g of N-formyl-1-(3-aminophenyl)-2-phenyl-2-propylamine, mp 114°-115° C. To a stirred solution of sodium nitrate (2.0 g, 0.03mol) in sulphuric acid (15 ml) at 0° C. under nitrogen was added dropwise a solution of N-formyl-1-(3-aminophenyl)-2-phenyl-2-propylamine (7.0 g, 0.027 mol) in acetic acid (75 ml) and the solution was stirred 2.5 hours at a temperature less than 20° C. The above mixture was added to a solution of cuprous chloride (5.3 g, 0.054 mol) in concentrated HCl (50 ml) at 15° C., and the resulting solution was stirred at that temperature for 1 hour. The reaction mixture was poured into water (500 ml), basified with concentrated ammonium hydroxide, and extracted with chloroform (3×200 ml). The combined chloroform extracts were dried over magnesium sulphate and the solvent evaporated to a solid, 7.5 g. This solid was recrystallised from isopropanol (20 ml) to provide 3.2 g of N-formyl-1-(3-chlorophenyl)-2-phenyl-2-propylamine, mp 108°-109° C.
