反応手順
3.5 mol p-nitrobenzylchloride are dissolved in the hot in 2300 ml of ethanol and a solution of 3.8 mol potassium hydroxide in 1100 ml of aqueous ethanol (70:30) is added thereto drop by drop. After completion of the addition, cooling takes place in an ice bath to 0° C., the precipitate is filtered off and washed in hot water and warm aqueous alcohol (50:50). Drying is then carried out in a vacuum at 75° C. (yield: 83%).
