实验步骤: Fifteen grams of 2-(3-dimethylaminopropoxy)benzaldehyde and 8.1 g of glycinamide, hydrochloride are reacted in 300 ml of ethanol in the presence of 4.8 g of 85% potassium hydroxide as described in Example 1 to give 20 g of a crude semi-solid product. The crude product is triturated with 100 ml of isopropyl ether and cooled to yield 17.9 g of solid; melting point 71°-73° C. (sintering at 60° C.). to give 20 g of a crude semi-solid product The crude product is triturated with 100 ml of isopropyl ether cooled

实验步骤: A stirred solution of 15 g of 2-(3-dimethylaminopropoxy)benzaldehyde and 10.2 g of glycine, ethyl ester, hydrochloride in 300 ml of ethanol is treated with 4.8 g of 85% potassium hydroxide and stirring continued for 3 hours at room temperature. Potassium chloride is filtered off, washed with ethanol, and the solvent is removed on a rotary evaporator (water bath temperature, 30°-35° C.). The residue is dissolved in ether, filtered, and the evaporation repeated to give 20.9 g of an oil. The material is stored in the cold. Potassium chloride is filtered off washed with ethanol the solvent is removed on a rotary evaporator (water bath temperature, 30°-35° C.) The residue is dissolved in ether filtered the evaporation
