实验步骤: A 5 ml portion of acrylic acid chloride and 200 ml of diethyl ether were put into a 500 ml capacity eggplant type flask and stirred on an ice bath. Next, 2 g of glutamineamide hydrochloride (mfd. by Kokusan Kagaku) was dissolved in 25 ml of deionized water, and 3 g of potassium carbonate was dissolved in 25 ml of deionized water. The glutamineamide aqueous solution was mixed with the potassium carbonate aqueous solution. The mixed liquid was added dropwise into the eggplant type flask spending 10 minutes while stirring constantly, and the mixture after completion of the dropwise addition was stirred for 24 hours. Diethyl ether layer in the thus obtained reaction liquid was discarded, and the water layer was concentrated at 25° C. under a reduced pressure. A 500 ml portion of acetone was added to the thus obtained residue and stirred for 1 hour. The insoluble solids were removed by suction filtration. By recrystallizing from the acetone layer, 0.25 g of colorless crystals were obtained. The mixed liquid was added dropwise into the eggplant type flask while stirring constantly the mixture after completion of the dropwise addition was stirred for 24 hours the water layer was concentrated at 25° C. under a reduced pressure A 500 ml portion of acetone was added to the thus obtained residue stirred for 1 hour The insoluble solids were removed by suction filtration By recrystallizing from the acetone layer
