A mixture of 27 parts of 4-phenyl-n-butanol with 23 parts of N,N-dimethylcyclohexylamine, and 31.7 parts of 5-chloro-6-methyl-3-methoxy-6H-1,2,4,6-thiatriazine-1,1-dioxide, were added side by side, in the course of 15 minutes, to 250 parts of methylene chloride at from 10° to 15° C., while stirring. Stirring was continued for one hour at room temperature, after which the reaction mixture was washed with 1N hydrochloric acid and with 10% strength sodium carbonate solution, and dried over magnesium sulfate. After evaporating down under reduced pressure, 40 parts of the 6-methyl-3-methoxy-5-(4-phenylbutoxy)-6H-1,2,4,6-thiatriazine-1,1-dioxide of melting point 74°-78° C. were obtained.
