실험 절차

2.22 g of 2-isopropoxy-6-trifluoromethyl-4-hydroxypyrimidine and 0.86 g of copper(I) oxide were suspended in 50 ml of octane. The suspension was refluxed until no water was recognized to form, while formed water was being taken into a quantitative water receiver. 1.86 g of triethyl phosphite was added, and, 30 minutes later, 3.65 g of methyl 3-methoxy-2-(2-bromomethylphenyl)acrylate was added at an instance. The reaction was carried out for 6 hours at reflux of octane. The solution was cooled down to room temperature. 20 ml of acetone was added to it. Insoluble matter was filtrated and washed with 10 ml of acetone twice. The mixed solution of the obtained filtrate and washings was analyzed with high-performance liquid chromatography. Yields were 82.1% for the target compound, and as for byproducts 3.1% for methyl 3-methoxy-2-[2-(2-isopropoxy-6-trifluoromethylpyrimidin4-on-3-ylmethyl)phenyl]acrylate and 14.8% for 4-(α-methoxy)methylen-2H-chromen-3(4H-one.
