Reaction Steps

A mixture of 2-nitrobenzoyl chloride (0.190 g), 5-[4-(1,3-dioxolan-2-yl)phenyl]-1H-tetrazole (0.200 g) and pyridine (5 ml) was heated under reflux for 1 hr. After cooling, water was added to the reaction mixture, and the crystals were collected by filtration, and dissolved in ethyl acetate. This solution was washed with 1 M hydrochloric acid, water and saturated brine, dried over anhydrous magnesium sulfate and concentrated. The residue was washed with hexane to give 2-[4-(1,3-dioxolan-2-yl)phenyl]-5-(2-nitrophenyl)-1,3,4-oxadiazole (0.240 g, yield 77%). Recrystallization from hexane-ethyl acetate gave colorless prism crystals. melting point: 88–89° C.
