Procedure

A mixture of 2-(3-bromo-4-fluorophenethyl)-5-(pyrimidin-5-ylmethyl)pyrimidin-4(1H)-one (1.5 g, 3.7 mmol), copper(I) cyanide (399 mg, 4.4 mmol) in NMP (5 mL) was heated with a microwave reactor at 200° C. for 1.5 h. After cooling to room temperature, the mixture was filtered. The filtrate was partitioned between ethyl acetate (20 mL) and water (30 mL). The organic phase was collected, washed with water (30 mL×2), brine (20 mL), dried over Na2SO4, filtered, and concentrated to give the title compound as a gray solid (1.0 g, 55% yield), which was used without further purification. LCMS: rt=1.31 min, [M+H+]=336
