실험 절차

A solution of 5.8 g (0.02 mole) 5-chloro-4-hydroxy-6-methyl-2-trichloromethylpyrimidine, 3.2 g (0.02 mole) 2-fluorobenzoyl chloride, and 2.0 g (0.02 mole) triethylamine in 100 ml diethyl ether was refluxed for 17 hours. After removal of triethylamine hydrochloride by filtration, the filtrate was concentrated in-vacuo to leave 8.4 g of residue, which, after recrystallization from ligroin, gave 4.6 g (59% yield) of pure product; m.p. 101° C.
