The solution was shaken 30 minutes at room temperature. Benzoyl chloride (1.43 mL, 12.346 mmol) was added drop by drop and the resulting solution was shaken at room temperature until full conversion as determined by thin-layer chromatography. Carbonated water (20 mL) was added three times. The organic phase was dried over magnesium sulfate, filtered and the solvent was removed under reduced pressure, thus affording 2.7080 g of a white solid corresponding to 3-nitrophenyl benzoate (11.144 mmol, yield=90%).
