Potassium Carbonate → HCID 22732528, compound

Participants

Reaction Steps

A mixture of 4-chloro-2-(3-pyridinyl)-6-trifluoromethyl-pyrimidine (42 mg, 0.162 mmol), 1H-5-indolylamine (31 mg, 235 mmol) and potassium carbonate (25 mg, 0.180 mmol) was heated overnight in 1 mL of DMF at 100° C. in a sealed tube. The reaction mixture was cooled to room temperature, diluted with 20 mL of ethyl acetate, washed with water (20 mL×3) and saturated NaCl. The organic layer was dried over Na2SO4, filtered, concentrated and the residue was purified by flash column chromatography (30% ethyl acetate/hexanes) to obtain the title compound as a white solid (mp 142–143° C., 45 mg, 0.127 mmol, 78%). 1H NMR (CDCl3): 9.56 (d, J=1.5 Hz, 1H), 8.74 (dt, J=1.8, 8.1 Hz, 1H), 8.63 (dd, J=3, 5.1 Hz, 1H), 7.66 (m, 1H), 7.46 (m, 2H), 7.30 (d, J=3 Hz, 1H), 7.19 (m, 1H), 6.82 (s, 1H), 6.55 (d, J=3 Hz, 1H).
