A solution of 10 mL (95.4 mMol) 1,2-diamino-2-methylpropane and 20 mL (144 mMol) triethylamine in 300 mL dichloromethane was cooled to 0° C. To this solution was added a solution of 26 gm (93.3 mMol) (triphenyl)methyl chloride in 50 mL dichloromethane. The resulting mixture was stirred at room temperature for about 18 hours. The reaction mixture was washed with saturated aqueous sodium bicarbonate, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was subjected to silica gel chromatography, eluting with ethyl acetate containing from 0–10% methanol. Fractions containing product were combined and concentrated under reduced pressure to provide 16.0 gm (52%) of the desired compound as a white solid.
