反応手順

To a solution of 3.0 g (0.02 mole) 4-hydroxy-6-methyl-2-trichloromethylpyrimidine and 1.3 g (0.02 mole) triethylamine in 75 ml diethyl ether was added 1.4 g (0.02 mole) crotonyl chloride. The reaction mixture was refluxed for 15 hours and filtered, and the filtrate was concentrated in-vacuo to give a viscous oil as residue. Trituration with petroleum ether caused the oil to solidify. Recrystallization from isopropyl alcohol gave 1.8 g (45% yield) of pure product; m.p. 55° C.
