Reaction Steps

Into a 100 ml reaction flask equipped with a stirrer, a thermometer and a condenser, 5.2 g (0.02 mol) of 2-anilino-4-methyl-6-(2-chloropropen-1-yl)pyrimidine, 1.3 g (0.024 mol) of finely pulverized KOH and 50 ml of toluene were charged, and the mixture was reacted for 10 hours under reflux. The reaction mixture was cooled, water was added, and the mixture was subjected to liquid separation. The toluene layer was washed with water. The toluene layer was concentrated and subjected to column chromatography to obtain 1.67 g of 2-anilino-4-methyl-6-(1-propynyl)pyrimidine having a melting point of from 125° to 126° C. The yield was 37.4%.
