Procedure

HATU (0.154 g, 0.41 mmol) and (+)-(trans)-2-{4-[({4-methyl-2-[4-(trifluoromethyl)phenyl]-1,3-thiazol-5-yl}methyl)amino]phenyl}cyclopropanecarboxylic acid (III-3c) (0.135 g, 0.31 mmol) in DMF (10 mL) were stirred at RT for 15 min, then hydroxylamine hydrochloride (0.50 g) was added. The solution was stirred at RT for 1 h, then saturated NaHCO3 solution (20 mL) was added. The resulting solid was filtered, washed with water (10 mL) and dissolved in ethyl acetate (50 mL). The organic layer was dried over MgSO4, filtered and concentrated to give the title compound as a white powder (0.067 g, 48%). 1H NMR (400 MHz, DMSO) δ 10.45 (s, 1H), 8.68 (s, 1H), 8.02 (d, J=8.1 Hz, 2H), 7.77 (d, J=8.3 Hz, 2H), 6.82 (d, J=8.5 Hz, 2H), 6.51 (d, J=8.6 Hz, 2H), 6.21 (t, J=5.7 Hz, 1H), 4.38 (d, J=5.9 Hz, 2H), 2.42 (s, 3H), 2.07-2.02 (m, 1H), 1.48-1.43 (m, 1H), 1.21-1.16 (m, 1H), 1.06-1.01 (m, 1H).
