Procedure

Combine 4-cyanobenzoic acid (30 mg, 2.07 mmol), tert-butylamine (0.5 mL, 4.13 mmol), triethylamine (0.4 mL, 2.89 mmol), and HATU (1.1 g, 2.89 mmol) in anhydrous DME (7 mL). Stir at ambient temperature for 17 h. Partition the reaction mixture between brine (15 mL) and diethyl ether (15 mL), separate the organic layer, dry over anhydrous Na2SO4 and concentrate in vacuo. Purify by chromatography on silica gel eluting with DCM to obtain the desired intermediate as a white solid (0.4 g, 89%). MS (ES+) m/z: 203 (M+H)+.
