Versuchsvorschrift

To 75 milliliters of methylene chloride maintained at 0°-5° C. via an ice bath were added 1.4 grams of 4-methyl-6-methoxy-2-amino-1,3,5-triazine and 1.55 grams of chlorosulfonyl isocyanate. After stirring for 3 hours at ice bath temperature a methylene chloride solution containing 1.0 gram of triethylamine and 1.37 grams of 2-(1-hydroxyethyl)aniline was added dropwise. The reaction mixture was removed from the ice bath, allowed to stir an additional one-half hour and then poured into 100 milliliters of 2 percent aqueous hydrochloric acid solution. After phase separation, the organic layer was washed in water and concentrated on a rotary evaporator affording a dark oil. Addition of diethyl ether to the dark oil resulted in the formation of a precipitate which was filtered-off. The filtrate was evaporated and the residue was taken-up in chloroform and again evaporated affording a powdery solid. Vacuum drying afforded 1.7 grams of light tan solid confirmed by NMR analysis as the desired product.
