Reaction Steps

To a solution of N-(2-bromo-5-methoxy-4-methyl-phenyl)-isobutyramide (6.83 g) in DMSO (40 mL) was added powder KOH (2.68 g, 47.7 mmol) and 4-methoxybenzyl chloride (7.5 g, 47.7 mmol) under argon. The mixture was stirred at room temperature for 17 hours. Water (30 mL) was added and the mixture extracted with EtOAc, washed with brine, dried over MgSO4, filtered and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (hexane:EtOAc/10:1 t0 3:1) to give 8.72 g of N-(2-bromo-5-methoxy-4-methyl-phenyl)-N-(4-methoxy-benzyl)-isobutyramide (90%). 1H NMR (300 MHz, CDCl3, ppm): δ: 1.00 (d, J=7.03 Hz, 3 H), 1.13 (d, J=6.45 Hz, 3 H), 2.17 (s, 3 H), 2.28 (m, 1 H), 3.48 (s, 3 H), 3.78 (s, 3 H), 3.84 (d, J=14.07 Hz, 1 H), 5.62 (d, J=14.07 Hz, 1 H), 6.06 (s, 1 H), 6.78–6.81 (m, 2 H), 7.10–7.13 (m, 2 H), 7.38 (s, 1 H).
