Versuchsvorschrift
4.47 g of 2,4-dichlorophenacyl chloride and 2.66 g of 4-n-butyl-thiosemicarbazide are reacted under the conditions of Example 2 in 150 ml of methanol. The solid obtained is recrystallized from methanol/ethyl acetate, producing 3.98 g of N-butyl-5-(2,4-dichlorophenyl)-6H-1,3,4-thiadiazin-2-amine monohydrochloride. m.p. 180°-182° C.
