Dimethylformamide → HCID 22024319, compound

Participants

Reaction Steps

Ammonium chloride (6.84 g, 0.126 mol) and potassium cyanide (13.68 g, 0.210 mol) were added to a mixed solution (100 mL) of a 15% aqueous solution of (E)-4-(2,4-dimethylphenyl)-3-butene-2-one (18.32 g, 0.105 mol) and N,N-dimethylformamide, and the mixture was heated under reflux for 6 hours. Water was added to the reaction mixture, which was extracted with ethyl acetate. The organic layer was washed with an aqueous saturated sodium bicarbonate solution and brine, dried over anhydrous magnesium sulfate and evaporated. The residue was purified by silica gel column chromatography (ethyl acetate:n-hexane=1:5) to give the title compound (10.13 g, 48%).
