Procedure

A solution of the final product from Example 86 (200 mg) in dry THF (5 ml) was added to liquid ammonia (15 ml) (purified by treating the liquid ammonia with sodium and distilling the ammonia into another flask). The mixture was cooled in a dry ice acetone bath at -35° C., in a flask fitted with an acetone dry ice condenser, and small pieces of sodium were added until the blue colour persisted. After 15 minutes ammonium chloride (0.1 g) was added and the ammonia allowed to evaporate. Ethanol (10 ml) was added to the mixture followed by water (10 ml) and the solvent largely removed under reduced pressure. The residue was diluted with water and extracted with dichloromethane to give a residue which was purified by flash column chromatography on silica using methanol/ethyl acetate (1:1) as the mobile phase to give 3-(imidazol-2-yl)-N-(1-methyl-1-phenylethyl)propylamine as an oil.
