Reaction Conditions

Reaction Steps

A mixture of 2,4-dichloro-pyrimidine-5-carbonitrile (2.0 g, 11.5 mmol), 2-(1H-indol-3-yl)-ethylamine (1.83 g, 11.4 mmol), and DIEA (1.94 g, 15.0 mmol) in THF (50 mL) was stirred at 50° C. for 3 h. After cooling to room temperature, the reaction mixture was concentrated and the residue was diluted with ethyl acetate (150 mL). The organic layer was washed with saturated aqueous ammonium chloride, brine, dried over anhydrous sodium sulfate and filtered. The filtrate was evaporated in vacuum to give the crude product, which was purified by silica gel column chromatography (20% ethyl acetate in petroleum ether) to afford the title compound as a brown solid (1.3 g, 4.38 mmol, 38% yield). MS (ESI) m/z 298.1 [M+H]+.
