실험 절차
15 ml of 40% strength by weight aqueous potassium hydroxide solution were slowly added to a suspension of 30.1 g (0.22 mol) of 4-amino-5-formyl-2-methylpyrimidine and 31.7 g (0.23 mol) of 4-fluoroacetophenone in 395 ml of methanol at 20°-25° C., a homogeneous solution being formed. After the mixture had been stirred for 20 hours at about 20° C., the solid formed was isolated and was recrystallized from ethanol. Yield: 50%; mp.>200° C.
