5.2 g of N-(4-methoxy-6-methyl-1,3,5-triazin-2-yl)-phenylcarbamate are added to a solution of 5 g of 2-(3,3,3-trifluoro-1-propen-1-yl)-phenylsulfonamide and 3.3 g of 1,5-diazabicyclo[5,4,0]undec-5-one in 80 ml of dioxan, and the mixture is stirred for 3 hours at 20°-25° C. The clear reaction solution is then taken up in 300 ml of water and the aqueous solution is acidified with 2N hydrochloric acid to pH 4-5. The resinous precipitate is extracted from the aqueous phase with ethyl acetate and the organic extract is dried and concentrated.
