실험 절차

A solution of 3.5 g of 3-[4-chloro-3-formylphenyl]-2,4-dioxo-1-methyl-6-trifluoromethyl-1,2,3,4-tetrahydropyrimidine, 0.8 g of 1,3-propanediol and 0.2 g of p-toluenesulfonic acid in 100 ml of anhydrous dichloromethane was boiled for 5 hours under a water separator. The solution was washed with 10% strength sodium bicarbonate solution and water, dried over sodium sulfate and evaporated down. The residue was chromatographed over silica gel (7:3 cyclohexane/ethyl acetate).
