実験手順

A mixture consisting of 4.9 gm., 0.02 mole, of 2-(2-chloro-5-thiadiazolyl)-1-methyl-5-nitroimidazole, 3.0 gm., 0.05 mole, of ethanolamine, and 50 ml. of p-dioxane is stirred at room temperature for twenty-four hours. The precipitate is collected, washed with aqueous sodium bicarbonate solution, dried and recrystallized from methanol to give the pure compound melting at 208°-209° C. Working up the mother liquors gives additional material, the total yield being 3.4 gm.
