Procedure

A mixture of 3-methyl-pyrrolo[3,2-c]pyridin-1-ylamine (224 mg, 1.52 mmol), 2-(3-fluoro-phenyl)-4-methyl-pyrimidine-5-carboxylic acid (354 mg, 1.52 mmol), HATU (693 mg, 1.82 mmol) and DIPEA (593 mg, 4.59 mmol) in DMF (8 mL) is heated at 1500 C. for 1 h. The reaction is quenched with water, NaHCO3 (168 mg, 2 mmol) is added and the mixture is extracted with EtOAc. The organic layer is separated, dried (Na2SO4), filtered and concentrated. The residue is first purified by silica gel column chromatography eluting with 10% MeOH in DCM and then recrystallized from EtOAc to afford 2-(3-fluoro-phenyl)-4-methyl-pyrimidine-5-carboxylic acid (3-methyl-pyrrolo[3,2-c]pyridin-1-yl)-amide (198 mg). MS: 362 (M+H); 1H NMR (300 MHz, CD3OD): δ 9.12 (s, 1H), 8.86 (s, 1H), 8.35 (d, 1H), 8.15-8.31 (m, 2H), 7.47-7.60 (m, 2H), 7.35 (s, 1H), 7.29 (t, 1H), 2.84 (s, 3H), 2.44 (s, 3H).
