4-(4,6-Dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride → 2-(3-Fluoro-phenyl)-4-methyl-pyrimidine-5-carboxylic acid (6-trifluoromethyl-indol-1-yl)-amide

Reaction Steps

A solution of 2-(3-fluoro-phenyl)-4-methyl-pyrimidine-5-carboxylic acid (278 mg, 1.2 mmol) and 6-trifluoromethyl-indol-1-ylamine (200 mg, 1 mmol) in DMF (5 mL) is stirred at 50° C. for 0.5 h. The mixture is treated with DMTMM (290 mg, 1.05 mmol) and stirred at 50° C. for 1 h. The mixture is diluted with saturated aqueous Na2CO3 (5 mL) and extracted with EtOAc (3×50 mL). The combined organic layer is dried (Na2SO4), filtered and concentrated in vacuo. The residue is triturated with Et2O/heptane overnight. The precipitate is collected by filtration, washed with H2O (50 mL) and heptane (50 mL), and dried in vacuo to afford 2-(3-fluoro-phenyl)-4-methyl-pyrimidine-5-carboxylic acid (6-trifluoromethyl-indol-1-yl)-amide (180 mg, 44%). MS: 415 (M+H); 1H NMR (300 MHz, DMSO-d6): δ 12.09 (s, NH, 1H), 9.33 (s, 1H), 8.35 (d, 1H), 8.20 (d, 1H), 7.90 (s, 1H), 7.79 (m, 2H), 7.65 (m, 1H), 7.46 (m, 2H), 6.74 (d, 1H), 2.79 (s, 3H).
