Procedure
13.4 mg (0.446 mmol) of an 80% strength suspension of sodium hydride in mineral oil (suspended in hexane and decanted) are added in one portion to a solution of 150 mg (0.297 mmol) of (2S*,4R*)-2-benzyl-1-(3,5-dichlorobenzoyl)-N-(4-quinolylmethyl)-4-piperidinamine in 2 ml of 1,2-dimethoxyethane at 0° C. After 10 minutes at 0° C., the mixture is left to stir at RT for 30 minutes, again cooled to 0° C., and 22 μl (0.357 mmol) of methyl iodide are added. The mixture is then stirred at RT for 96 hours. The solvent is stripped off in a rotary evaporator, and the residue is chromatographed on silica gel with toluene/ethyl acetate (1:1). The title compound ##STR78## is obtained (20 mg, 13%) as white foam. TLC:toluene/ethyl acetate (1:1) Rf =0.45; FD-MS:M+ =517, 519.
