실험 절차

To a mixture of 2-aminomethyl-4-benzylmorpholine (3.1 g), 2-acetoxy-4-acetylamino-5-chlorobenzoic acid (4.0 g), and dichloromethane (40 ml) is added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (2.9 g), and the mixture is stirred at 25° C. for 4 hours. The reaction mixture is washed successively with water and saturated aqueous sodium chloride solution, dried over magnesium sulfate, and evaporated under reduced pressure. The residue is dissolved in ethanol (80 ml), and 10% hydrochloric acid (30 ml) is added. The mixture is refluxed with stirring for 2 hours and concentrated under reduced pressure. The residue is neutralized with aqueous sodium bicarbonate solution and extracted with chloroform. The organic layer is washed successively with water and saturated aqueous sodium chloride solution, dried over magnesium sulfate, and evaporated under reduced pressure. The residue is recrystallized from isopropyl alcohol to give the monohydrate of the title compound (3.0 g), mp 153°-155° C.
