Procedure: A mixture of 4′-[(4-butyl-2-methyl-6-oxo-1,6-dihydropyrimidin-5-yl)methyl]biphenyl-2-carbonitrile (1.22 g), potassium carbonate (0.94 g), 1-[3-(bromomethyl)phenyl]ethanone (0.73 g) and N,N-dimethylformamide (20 mL) was stirred at 90° C. for 2 hr. The reaction mixture was diluted with ethyl acetate, washed with water and then with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography to give the title compound as a colorless viscous substance (1.02 g, 61%). washed with water with saturated brine, and dried over anhydrous magnesium sulfate The solvent was evaporated under reduced pressure the residue was purified by silica gel column chromatography

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 3-acetylbenzyl bromide (4 g) and ethyl acetoacetate sodium salt (3.42 g) in tetrahydrofuran (50 mL) was stirred for 12 hr. The insoluble material was filtered off and the filtrate was concentrated. The residue was purified by silica gel column chromatography to give the title compound (2.42 g, 49%) as a colorless viscous oil. The insoluble material was filtered off the filtrate was concentrated The residue was purified by silica gel column chromatography

Procedure: N-(4-tert-butylbenzyl)methylamine (1.25 g; 7.04 mmol) and potassium carbonate (1.95 g; 14.1 mmol) were added to N,N-dimethylformamide (30 ml). While the mixture was stirred in an ice bath, 3′-bromomethylacetophenone (1.50 g; 7.04 mmol) in N,N-dimethylformamide (10 ml) was added dropwise. After completion of the addition, the mixture was removed from the ice bath, and stirred for 1 hour at room temperature. Reaction was stopped by pouring the mixture into ice+saturated aqueous sodium bicarbonate solution, followed by extraction with ethyl acetate (100 ml). The organic layer was washed with saturated aqueous sodium bicarbonate solution and then with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (chloroform), to thereby yield 1.42 g of the target compound as pale yellow oily matter (yield: 65.2%).
