Reaction Steps

A mixture of N-[4-cyano-3-(trifluoromethyl)phenyl]-N-(cyclopropylmethyl)glycine (0.298 g, 1 mmol), di-tert-butyl dicarbonate (0.436 g, 2 mmol), pyridine (0.100 g, 1.25 mmol), and ammonium hydrocarbonate (0.160 g, 2.25 mmol) was stirred for 24 h in acetonitrile (8 mL). The solvent was removed under reduced pressure, then water (10 mL) was added to the residue. The resulting solid was filtered, washed with water (3×5 mL), and then dried. After drying, the solid was suspended in diethyl ether (10 mL) and stirred for 12 h. The mixture was filtered, washed with diethyl ether (5 mL), and dried to obtain 0.118 g (40%) of the title compound as a white solid: 1H NMR (400 MHz, CDCl3) δ 7.63 (d, J=8.6 Hz, 1H), 7.03 (d, J=2.3 Hz, 1H), 6.84 (dd, J=8.8, 2.5 Hz, 1H), 6.02 (bs, 1H), 5.57 (bs, 1H), 4.10 (s, 2H), 3.38 (d, J=6.6 Hz, 2H), 1.08 (m, 1H), 0.67 (m, 2H), 0.33 (m, 2H).
