반응 단계
A mixture of 28.6 g of dichloroethyl ether, 13.2 g of malononitrile, 55.28 g of potassium carbonate and 800 ml of acetonitrile was refluxed on a steam bath for 24 hours, then filtered while hot. The filtrate was evaporated and the residue crystallized, with charcoal treatment, from 100 ml of ethanol, giving 9.5 g of tetrahydro-4H-pyran-4,4-dicarbonitrile as colorless plates, mp 110°-112° C.
