A solution of 2-pyrimidin-2-yl-4-methyl-pyrimidine-5-carboxylic acid (496 mg, 2.30 mmol) and 5-methoxy-indol-1-ylamine (0.98 mmol) in anhydrous DMF (10 mL) is stirred at 50° C. for 30 min. DMTMM (555 mg, 2.01 mmol) is added and stirred at 50° C. for an hour. DMF is evaporated off. The residue is mixed with water (40 mL) and stirred at rt for 20 minutes. The solid is collected by filtration, washed with water (3×5 mL) and dried in vacuum to afford 2-pyrimidin-2-yl-4-methyl-pyrimidine-5-carboxylic acid (5-methoxyl-indol-1-yl)-amide (410 mg) as a solid. MS: 361 (M+H); 1H NMR (300 MHz, CD3OD): δ 2.93(s, 3H), 4.84(s, 3H), 7.04(t, H), 6.50(d, H), 6.92(d, H), 7.14(s, H), 7.26-7.37(m, 2H), 7.72 (t, H), 9.09 (d, 2H), 9.27(s, H).
