Reaction Steps

A solution of 2-(3-fluoro-phenyl)-4-methyl-pyrimidine-5-carboxylic acid (250 mg, 1.07 mmol) in DCM (10 mL) is cooled to 0° C., treated with DMF (20 μL) and ClCOCOCl (280 μL, 3.21 mmol), and stirred for 20 min. Toluene (10 mL) is added and the mixture is concentrated in vacuo. The residue is dissolved in pyridine (10 mL) and treated with DMAP (5 mg) and 1-(1-amino-5-fluoroindol-3-yl)-2-methyl-propan-2-ol (0.72 mmol). The mixture is stirred at rt for 12 h. The mixture is diluted with saturated aqueous Na2CO3, extracted with EtOAc. The organic layer is separated, dried (Na2SO4), filtered and concentrated in vacuo. The residue is purified by silica gel chromatography eluting with 20%-60% EtOAc in heptane to afford 2-(3-fluoro-phenyl)-4-methyl-pyrimidine-5-carboxylic acid [5-fluoro-3-(2-hydroxy-2-methyl-propyl)-indol-1-yl]-amide (218 mg, 70%). MS: 437 (M+H); 1H NMR (300 MHz, DMSO-d6): δ 1.14 (s, 6H), 2.77 (s, 2H), 3.29 (s, 3H), 7.03 (m, 1H), 7.37 (s, 1H), 7.35-7.55 (m, 3H), 7.65 (m, 1H), 8.19 (m, 1H), 8.34 (m, 1H), 9.22 (s, 1H).
