Participants

Reaction Steps

A mixture of 3-bromo-2-methylaniline (0.764 mL, 6.20 mmol), 1,3-thiazol-2-ylacetic acid (0.74 g, 5.17 mmol) and DIEA (1.63 mL, 9.30 mmol) in DMF (15 mL) was treated with HATU (2.36 g, 6.20 mmol). After stirring overnight, the mixture was diluted with EtOAc, washed twice with 10% aqueous LiCl followed by brine, and the combined aqueous layers were extracted with EtOAc. The combined organic layers were dried and concentrated, and the residue was purified by column chromatography on silica gel, eluting with EtOAc-hexanes, to give N-(3-bromo-2-methylphenyl)-2-(thiazol-2-yl)acetamide as a white solid (0.681 g, 42% yield). 1H NMR (400 MHz, chloroform-d) δ 9.84-9.65 (m, 1H), 7.91 (d, J=7.9 Hz, 1H), 7.84 (d, J=3.3 Hz, 1H), 7.42-7.35 (m, 2H), 7.07 (t, J=8.0 Hz, 1H), 4.18 (s, 2H), 2.38 (s, 3H).
