A mixture of 3-methyl-pyrrolo[3,2-b]pyridin-1-yl amine (75% pure) (240 mg, <1.63 mmol), 2-(3-fluoro-phenyl)-4-methyl-pyrimidine-5-carboxylic acid (379 mg, 1.63 mmol), HATU (744 mg, 1.96 mmol) and DIPEA (388 mg, 4.89 mmol) in DMF (5 mL) is heated at 1500 C. for 1 h. The reaction is quenched with water, extracted with EtOAc. The organic layer is dried (Na2SO4), filtered and concentrated. The residue is chromatographed through silica gel eluting with 10% MeOH in DCM. The resulting product is recrystallized with ether to afford 2-(3-fluoro-phenyl)-4-methyl-pyrimidine-5-carboxylic acid (3-methyl-pyrrolo[3,2-b]pyridin-1-yl)-amide (197 mg, 44%). MS: 362 (M+H); 1H NMR (300 MHz, CD3OD): δ 9.14 (s, 1H), 8.40 (d, 1H), 8.36 (d, 1H), 8.22 (d, 1H), 7.85(d, 1H), 7.55 (q 1H), 7.47 (s, 1H), 7.25-7.34 (m, 2H), 2.83 (s, 3H), 2.42(s, 3H). IC50=2 nM.
