Reaction Conditions

Reaction Steps

To a solution of 201 mg (0.83 mmol) of 1-(6-2-hydroxyethyl-methylamino-2-naphthyl)-1-ethanone in pyridine (6 mL), malononitrile (236 mg, 3.6 mmol) was added and the mixture was heated at 95° C. for 24 hours. The solvent was removed in vacuo, and the residue was chromatographed by radial chromatography (4 mm SiO2 1% MeOH/CH2Cl2) to give 150 mg (73%) of 2-(1,1-dicyanopropen-2-yl)-6-2-hydroxyethyl)-methyl-amino)-naphthalene.
