Cyclohexylamine → 2-(2-Cyclohexylamino-5-thiadiazolyl)-1-methyl-5nitroimidazole

関与物質

反応手順

A mixture of 5.0 g. of 2-(2-chloro-5-thiadiazolyl)-1-methyl-5-nitroimidazole, 6.0 g. of cyclohexylamine and 125 ml. of dioxane is stirred at reflux until thin-layer chromatographic analysis indicates that the chloro intermediate is completely utilized. The dioxane is removed under reduced pressure and the residue triturated with aqueous sodium bicarbonate solution. Recrystallization from a mixture of ethylacetate and acetone yields the pure compound melting at 215°-217° C.
