2-Pyrimidinamine, 4-chloro-6-methoxy- → Chlorimuron-ethyl

Participants

Reaction Steps

To 1.0 g of 2-amino-4-chloro-6-methoxypyrimidine suspended in 25 ml of dry CH2Cl2 was added 1.53 g of ethyl 2-(isocyanatosulfonyl)benzoate (prepared by procedures taught in U.S. Pat. No. 4,305,884). The reaction mixture was stirred at ambient temperature for three days. The solvent was stripped and the product was recrystallized from butyl chloride to give a white solid with m.p. 198°-201°.
