실험 절차
To 37.5 ml of ice-cooled acetic acid solution of 25% hydrobromic acid was added 3.22 g of compound (54) and the reaction was maintained for 3 hours at room temperature. The reaction mixture was added to 375 ml of dry ether and the precipitates thus formed were quickly collected by filtration and dried overnight in a desiccator containing potassium hydroxide to provide 4.43 g of L-histidyl-N-(2-acetoxyethyl)-L-prolinamide.2-hydrobromide.
