Versuchsvorschrift

A mixture of 3-methyl-5-trifluoromethyl-indol-1-ylamine (223 mg, 1.04 mmol), 4-methyl-2-pyridin-2-yl-pyrimidine-5-carboxylic acid (224 g, 1.04 mmol), HATU (475 mg, 1.25 mmol), DIPEA (404 mg 3.13 mmol) is stirred in DMF at 150° C. for 1 h. The reaction is quenched with water, extracted with 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 to afford 4-methyl-2-pyridin-2-yl-pyrimidine-5-carboxylic acid (3-methyl-5-trifluoromethyl-indol-1-yl)-amide (122 mg, 28%). MS: 412 (M+H); 1H NMR (300 MHz, CD3OD): δ 9.22 (s, 1H), 8.79 (d, 1H), 8.66 (d, 1H), 8.06 (t, 1H), 7.91 (s, 1H), 7.60 (dd, 1H), 7.51 (s, 2H), 7.29 (s, 3H), 2.88 (s, 3H), 2.40 (s, 3H).
