Participants

Reaction Steps

4.2 g of phenol (45 mmol) were added at 25° C. to a solution of 9.9 g of 2-isocyanato-4-methoxy-6-trifluoromethylpyrimidine (45 mmol) in 50 ml of methylene chloride. Stirring was carried out for 16 hours at 25° C., the methylene chloride was distilled off under reduced pressure and the residue was stirred vigorously with 100 ml of a diisopropyl ether/hexane mixture (v/v 1:20), whereupon crystallization occurred. The product was filtered off with suction and dried under reduced pressure from a water pump at 50° C. The title compound (12.2 g; 87% of theory) was obtained as colorless crystals of melting point 85°-88° C.
