実験手順
A mixture of 6-(4-chlorophenyl)-3-hydrazino-5-methyl-1,2,4-triazine (7 g), 2-iodomethylthio-2-imidazoline (8.11 g) and n-butanol (50 ml) was refluxed for 3 hours with stirring. After cooling, the mixture was evaporated under reduced pressure and the residue was dissolved in 1N hydrochloric acid. The solution was washed with ethyl acetate and made alkaline with an aqueous solution of potassium carbonate. The resultant precipitates were collected by filtration, washed with water, dried and recrystallized from methanol and then from ethanol to give dark red crystals of 6-(4-chlorophenyl)-3-[2-(2-imidazolin-2-yl)hydrazino]-5-methyl-1,2,4-triazine (1.53 g), m.p. 230°~231° C. (decomp.).
