Procedure

A solution of tert-butyl (3-amino-2-methylpropyl)carbamate (200 mg, 1.06 mmol), 4-cyanobenzoic acid (156 mg, 1.06 mmol), HATU (525 mg, 1.38 mmol) and TEA (0.444 mL, 3.19 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; 10 to 50% ethyl acetate/hexane) to give tert-butyl (3-(4-cyanobenzamido)-2-methylpropyl)carbamate (311 mg, 0.980 mmol, 92%) as a white powder.
