(Z)-Benzaldehyde oxime → HCID 67099896, compound

Participants

Reaction Steps

A solution of benzaldehyde oxime (0.37 mL, 3.7 mmol) in dry DMF (4 mL) was added to a stirred suspension of NaH (0.16 mL, 3.7 mmol) in dry dioxane (50 mL) in a nitrogen atmosphere at room temperature. After 30 minutes, a solution of ethyl 3-(2-(2-cyano-1-ethoxy-1-oxopropan-2-yl)phenyl)propiolate (1.12 g, 3.7 mmol) was added in dry DMF (5 mL), and the solution was stirred overnight. The solvent was removed under vacuum, and water was added to the residue. The product was extracted with EtOAc. The organic layer was washed with water, dried with MgSO4, concentrated in vacuo, and purified by silica flash chromatography eluting with 0-30% EtOAc/hexane. MS (m/z)=272 (M+H)+.
