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

Reaction Steps

A solution of 2-(3-fluoro-phenyl)-4-methyl-pyrimidine-5-carboxylic acid (232 mg, 1 mmol) and 5-fluoro-3-(2-pyridin-3-yl-ethyl)-indol-1-ylamine (255 mmol) in DMF (10 mL) is stirred at 50° C. for 10 min. The mixture is treated with DMTMM (276 mg, 1 mmol) and stirred at 50° C. for 0.5 h. The mixture is diluted with saturated aqueous Na2CO3 (50 mL), and extracted with EtOAc (3×50 mL). The combined organic layer is dried (Na2SO4), filtered and concentrated in vacuo. The residue is purified by triturating in MeOH:H2O (2:1) to afford 2-(3-fluoro-phenyl)-4-methyl-pyrimidine-5-carboxylic acid [5-fluoro-3-(2-pyridin-3-yl-ethyl)-indol-1-yl]-amide (6 mg, 1%). MS: 470 (M+H); 1H NMR (300 MHz, DMSO-d6): δ 9.21 (s, 1H), 8.51 (m, 1H), 8.40 (m, 1H), 8.33 (d, 1H), 8.19 (d, 1H), 7.74 (d, 1H), 7.63 (m, 1H), 7.45 (m, 4H), 7.33 (m, 1H), 7.06 (m, 1H), 3.29 (s, 2H), 3.01 (s, 2H), 2.77 (s, 3H).
