실험 절차

To an ethanolic solution of sodium ethoxide [prepared from 555 mg (24 mg atom) of sodium in 50 ml of ethanol] is added diethyl malonate (3.52 g, 22 mmole) in 50 ml of absolute ethanol. After heating at reflux temperature for 2 hours, tetrahydro-3,5-bis(phenylmethylene)-4H-thiopyran-4-one (5.84 g, 20 mmole) is added. The resulting solution is then heated at reflux temperature for 2 hours.
