Reaction Steps

A 90 g (0.60 mole) portion of 4-chromanamine and 450 ml of ethanol were placed in a 2-l, 3-necked flask, equipped with a stirrer and reflux condenser fitted with a drying tube, and treated with 75 g (0.61 mole) of salicylaldehyde. The reaction mixture was refluxed for 8 hrs., stored overnight at room temperature, cooled and filtered. The yellow crystalline solid was washed with 150 ml of ethanol, ether and dried; m.p. 123°-126°. Yield: 126 g (83%).
