Reaction Steps

A solution of 2-(3-fluoro-phenyl)-4-methyl-pyrimidine-5-carboxylic acid (250 mg, 1.1 mmol) and 3-ethyl-5-trifluoromethoxy-indol-1-ylamine (244 mg, 1 mmol) in DMF (5 mL) is stirred at 50° C. for 1 h. The mixture is treated with DMTMM (276 mg, 1 mmol) and stirred at 50° C. for 1 h. The mixture is diluted with saturated aqueous Na2CO3 (5 mL) and stirred for 10 min. 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 (3-ethyl-5-trifluoromethoxy-indol-1-yl)-amide (270 mg, 59%). MS: 459 (M+H); 1H NMR (300 MHz, CDCl3): δ 11.51 (s, NH, 1H), 9.08 (s, 1H), 8.35 (d, 1H), 8.24 (d, 1H), 7.48 (m, 2H), 7.22 (m, 2H), 7.11 (m, 2H), 2.85 (s, 3H), 2.80 (q, 2H), 1.35 (t, 3H).
