반응 단계
3-Nitrobenzoic acid, hydrazide, 24.5 g, (Chemical Abstracts, Vol. 102, 148507r (1983)) and 1,1,1-triethoxyethane are refluxed overnight. The mixture is cooled, filtered, and washed with hexane to give 21.9 g of 2-methyl-5-(3-nitrophenyl)-1,3,4-oxadiazole after recrystallization from 2-propanol; mp 154°-156° C.
