YieldReaction ConditionsOperation in experiment
42% With sulfuric acid; nitric acid; at 0 - 20℃; for 1.16667h; Reference Example 13: 4-(4-Nitrophenyl) oxazole. 4-Phenyloxazole (1 g, 6.89 mmol) was dissolved in concentrated sulfuric acid (5 mL) at 0 0C. A cold solution of nitrating-mixture (prepared by adding 3 mL cone, nitric acid to 5 mL of ice-cold cone, sulfuric acid) was added over 10 minutes. The mixture was allowed to warm to r.t. and stirred for Ih. The resulting solution was poured into ice-cold water giving a white precipitate, which was filtered and washed thoroughly with water. The solid was dissolved in DCM and washed with water then brine. The organic phase was dried over sodium sulfate and concentrated to yield 4-(4- nitro-phenyl)-oxazole (550 mg, 42%) as a white solid.
