実験手順

A mixture of 4′-[(2-methyl-6-oxo-4-propyl-1,6-dihydropyrimidin-5-yl)methyl]biphenyl-2-carbonitrile (10 g), (2,2-dimethyl-4-oxo-3,4-dihydro-2H-chromen-6-yl)boronic acid (6.6 g), copper(II) acetate (5.5 g), pyridine (12 mL), triethylamine (21 mL), molecular sieves 4 A (20 g) and dichloromethane (100 mL) was stirred for 3 days. The reaction mixture was diluted with ethyl acetate, and the insoluble material was filtered off. The filtrate was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography to give the title compound (7.0 g, 45%) as a colorless solid.
