2-Bromo-N-isopropyl-N-(4-methoxyphenyl)acetamide (1e, 2.86 g) was dissolved in methanol saturated with ammonia at 0° C. and left for 3 days at room temperature in a sealed flask. Methanol and ammonia were removed in vacuo and the residue was dissolved in chloroform (100 ml) and washed with water (2×50 ml). The organic layer was separated and dried with anhydrous MgSO4 and concentrated in vacuo to afford the titled product (1f, 2.7 g). 1H NMR (300 MHz, CDCl3) 6.96 (m, 4H), 4.99 (sept., J=6.6 Hz, 1H), 3.84 (s, 3H), 2.97 (s, 2H), 1.58 (s, 2H), 1.05 (d, J=6.6 Hz, 6H),
