Participants

Reaction Steps

22 parts of 2-phenylethanol and 26.8 parts of tri-n-propylamine were added, in the course of 10 minutes, to 31.7 parts of 5-chloro-6-methyl-3-methoxy-6H-1,2,4,6-thiatriazine-1,1-dioxide in 200 parts of 1,2-dichloroethane at from 0° to 5° C., while stirring. Stirring was continued for 15 minutes at room temperature, after which the reaction solution was washed successively with 1N hydrochloric acid, with 0.5N sodium hydroxide solution and with water, dried over magnesium sulfate and chromatographed over neutral aluminum oxide. After evaporating down under reduced pressure, 36 parts (81% of theory) of 6-methyl-3-methoxy-5-(2-phenylethoxy)-6H-1,2,4,6-thiatriazine-1,1-dioxide of melting point 74°-77° C. were obtained.
