Procedure

A mixture of 3-ethyl-pyrrolo[2,3-b]pyridin-1-ylamine (126 mg, 0.78 mmol), 2-(3-Fluoro-phenyl)-4-methyl-pyrimidine-5-carboxylic acid (180 mg, 0.78 mmol), HATU (356 mg, 0.036 mmol) and DIPEA (302 mg, 2.34 mmol) in DMF (4 mL) is heated at 150° C. for 1 h. The reaction is quenched with water and extracted with EtOAc. The organic layer is dried (Na2SO4), filtered and concentrated. The residue is chromatographed through silica gel eluting with 0-100% ethyl acetate in heptane to afford 2-(3-fluoro-phenyl)-4-methyl-pyrimidine-5-carboxylic acid (3-ethyl-pyrrolo[2,3-b]pyridin-1-yl)-amide (128 mg). MS: 376 (M+H); 1H NMR (300 MHz, DMSO-d6): δ 9.10 (s, 1H), 8.25-8.33 (m, 2H), 8.16 (d, 1H), 8.05 (d, 1H), 7.62 (q, 1H), 7.39-7.48 (m, 2H), 7.16 (dd, 1H), 2.78 (s, 3H), 2.75 (q, 2H), 1.29(t, 3H).
