Reaction Steps

A solution of 4,4′-dichlorobenzhydryl chloride (3.22 g, 11.85 mmol) in a 1.85 M solution of methylamine in tetrahydrofuran (40 ml) was heated at 125° C. in a pressure vessel for 24 h. The cooled reaction mixture was diluted with ethyl acetate, washed with sodium carbonate, brine and dried (magnesium sulfate). Evaporation of the solvent and chromatography of the residue on silica gel (elution toluene-ethyl acetate 8:2) gave 2.12 g (67%) of the title amine as a clear oil. 1HNMR 400 MHz (CDCl3) δ (ppm): 2.57 (3H, s, NCH3), 4.85 (1H, s, CH benzhydryl), 7.0-7.53 (8H, m, aromatics). MS (ESI+) (m/z): 266 (M+H).
