A solution of 2.86 g of 2-bromo-N-isopropyl-N-(4-methoxy-phenyl)-acetamide (10 mmol) in 100 mL methanol is saturated with ammonia at 0° C. and left for 3 days at ambient temperature in a sealed flask. Methanol and ammonia were removed in vacuo and the residue is dissolved in 100 mL of chloroform and washed with water (2×50 mL). The organic layer is dried over anhydrous MgSO4, filtered, concentrated in vacuo and dried under high vacuum to afford 2.7 g of 2-Amino-N-isopropyl-N-(4-methoxy-phenyl)-acetamide as an oil: 1H NMR (300 MHz, CDCl3) δ6.96 (m, 4H), 4.99 (m, 1H), 3.84 (s, 3H), 2.97 (s, 2H), 1.58 (s, 2H), 1.05 (d, 6H, J=6.6); low resolution MS (ESI)m/e 223 (MH+).
