Procedure

To 0.80 g of 4,6-dimethoxy-2-methylamino-1,3,5-triazine in 25 ml of dry methylene chloride was added at ambient temperature 1.33 g of 2-difluoromethylthiobenzenesulfonyl isocyanate in 15 ml of methylene chloride. The reaction mixture was stirred for 16 hours and the resultant precipitate removed by filtration. It melted at 158°-164°, showed absorption peaks by Nuclear Magnetic Resonance (60MC) at:
