실험 절차

In 200 ml of methylene chloride was dissolved 21 g of the 3-(benzyloxycarbonylamino)propanol, and 11 g of triethylamine was added thereto, after which 8.6 g of acetyl chloride was added thereto dropwise at -10° C. to -5° C. The resulting mixture was subjected to reaction at the same temperature for 1 hour. Subsequently, at room temperature, the reaction mixture was washed successively with 50 ml of diluted hydrochloric acid, 50 ml of a saturated aqueous sodium hydrogencarbonate solution and 50 ml of water, and then dried over anhydrous magnesium sulfate, after which the solvent was removed by distillation under reduced pressure to obtain 28 g of oily 1-acetoxy-3-(benzyloxycarbonylamino)propane.
