실험 절차

To a stirred solution of 4-chloro-3-(6-methyl-2-oxo-4-trifluoromethyl-2H-pyrimidin-1-yl)-benzoic acid (50 mg, 0.151 mmol) in anhydrous 1,2-dichloroethane (0.5 mL) at room temperature was added oxalyl chloride (23 mg, 0.181 mmol) followed by a catalytic amount of DMF. After stirring for 40 mins, a solution of N-methyl-2-chloro-3-fluoroaniline 29-1 (30 mg, 0.188 mmol) in 1,2-dichloroethane (0.5 mL), followed by 4-(dimethylamino)pyridine (22 mg, 0.179 mmol) were added and the mixture was stirred for 12 h. Direct purification via reverse phase preparative LCMS gave 4-chloro-N-(2-chloro-3-fluoro-phenyl)-N-methyl-3-(6-methyl-2-oxo-4-trifluoromethyl-2H-pyrimidin-1-yl)-benzamide 30-1 (18 mg, 25%) as a colorless solid. MS: 350.5, tR=8.75 min (method 3); 1H NMR (CDCl3) δ 7.50 (1H, m), 7.44 (1H, dd, J=8.4, 1.8 Hz), 7.31 (1H, m), 7.26 (1H, s), 6.95 (1H, dd, J=9, 2.1 Hz), 6.79 (1H, m), 6.55 (1H, s), 3.46 (3H, s), 1.93 (3H, s).
