Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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

Procedure: 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

Procedure: 2-(3-Dimethylaminopropoxy)bezaldehyde (32.5 g) is reacted with 11.5 g of n-butylamine in 150 ml of toluene following the procedure described in Example 1, part A, to yield 37.9 g of oil product, boiling point 124°-128° C/0.1-0.2 mm of Hg.

Conditions: temp:50.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A solution of 32.5 g of 2-(3-dimethylaminopropoxy)benzaldehyde and 18.9 g of phenethylamine in 150 ml of toluene is heated at reflux for 1 hour. After 30 minutes, one mole equivalent of water is collected in a Dean-Stark trap. After cooling to approximately 50° C., the solvent is removed using a rotary evaporator and the oily residue is distilled to give 36.2 g of the title compound, boiling point 165°-167° C. at 0.05 mm of Hg. at reflux for 1 hour one mole equivalent of water is collected in a Dean-Stark trap the solvent is removed a rotary evaporator the oily residue is distilled
