実験手順

A mixture of 4′-[(2-methyl-6-oxo-4-propyl-1,6-dihydropyrimidin-5-yl)methyl]biphenyl-2-carbonitrile (1 g), 1,1′-(azodicarbonyl)dipiperidine (1.47 g), tributylphosphine (1.81 mL), (1-methyl-1H-indazol-3-yl)methanol (0.51 g) and tetrahydrofuran (50 mL) was stirred at room temperature for 4 hr. The reaction mixture was concentrated. 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 a colorless solid (0.67 g, 47%).
