Procedure

To a solution of 3-bromo-6-fluoro-2-methylbenzoic acid (Cpd QQ, 4.8 g, 2.4 mmol), 2-[(4-methoxybenzyl)amino]ethanol (130a, 5.5 g, 23 mmol) and DIPEA (8 g, 62 mmol) in dry DMF (80 mL) was added HATU (12 g, 31 mmol). The mixture was stirred at room temperature for 14 hours. To the reaction mixture was added EtOAc (130 mL). The solution was washed with brine (4×60 mL), dried over Na2SO4, and concentrated under vacuum. The residue was purified by column chromatography (petroleum ether/EtOAc, 2/1) to give 3-bromo-6-fluoro-N-(2-hydroxyethyl)-N-(4-methoxybenzyl)-2-methylbenzamide (130b, 4 g, 48.8%) as a colorless oil.
