Reaction Steps

A mixture of 4′-[(2-methyl-6-oxo-4-propyl-1,6-dihydropyrimidin-5-yl)methyl]biphenyl-2-carbonitrile (7 g), 1,1′-(azodicarbonyl)dipiperidine (9.9 g), tributylphosphine (12.2 mL), pyridin-2-ylmethanol (2.8 mL) and tetrahydrofuran (350 mL) was stirred at room temperature for 4 hr. The reaction mixture was concentrated, and the residue 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 colorless crystals (2.6 g, 31%).
