Reaction Steps

A solution of 3-((tert-butoxycarbonyl)amino)-2-methylpropanoic acid (200 mg, 0.98 mmol), 4-(aminomethyl)benzonitrile (130 mg, 0.98 mmol), HATU (486 mg, 1.28 mmol) and TEA (0.411 mL, 2.95 mmol) in DMF (5 mL) was stirred at room temperature for 16 hr. Water was poured into the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was dried, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (solvent gradient; 20 to 67% ethyl acetate/hexane) to give tert-butyl (3-((4-cyanobenzyl)amino)-2-methyl-3-oxopropyl)carbamate (221 mg, 0.696 mmol, 70.8%) as a white powder.
