Reaction Steps

A mixture of 4-bromo-3-methyl-benzoic acid (15 g, 0.069 mol), O,N-dimethyl hydroxylamine (6.5 g, 0.1 mol) HATU (38 g, 0.1 mol), and triethylamine (20 g, 0.2 mol) dissolved in DMF (50 mL) was stirred at RT for 12 h, concentrated, and purified by silica gel chromatography (1:1 EtOAc:petroleum ether) to provide the title intermediate (11 g, 61% yield) 1H NMR (CDCl3, 400 MHz) δ (ppm): 7.52 (m, 2H), 7.32 (m, 1H), 3.50 (s, 3H), 3.29 (m, 3H), 2.38 (s, 3H).
