Conditions

Temperature: 80 °C

Procedure

To a solution of 2-butyl-5-(3,3-dimethyl-2-oxobutyl)-6-methylpyrimidin-4(3H)-one (0.48 g) and 4′-(bromomethyl)biphenyl-2-carbonitrile (0.99 g) in N,N-dimethylformamide (9 mL) was added potassium carbonate (0.75 g), and the mixture was stirred at 80° C. for 24 hr. The reaction mixture was allowed to cool to room temperature, ethyl acetate and water were added, and the aqueous layer was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated and the residue was purified by silica gel column chromatography to give the title compound as a pale-yellow viscous substance (0.33 g, 40%).
