Acrylonitrile → 7-METHOXY-2H-CHROMENE-3-CARBONITRILE

Participants

Reaction Steps

To 2-hydroxy-4-methoxy-benzaldehyde (10.0 g, 65.72 mmol) and DABCO (1,4-diazabicyclo[2.2.2]octane) (1.84 g, 16.43 mmol) was added acrylonitrile (17.44 g, 328.62 mmol). The reaction mixture was refluxed for 20 h. The reaction mixture was diluted with ethyl acetate and the resulting rheum was separated. The organic phase was washed with a 1 molar solution of NaOH and then with a 1 molar solution of HCl. The organic layer was dried over magnesium sulfate, filtered, and the solvent evaporated under reduced pressure to give the crude product (8.89 g, 72% yield).
