HCID 21515750, compound → Ethyl 4-cyclohexylidenebut-2-enoate

Participants

Reaction Steps

Ethyl 4-cyclohexylidene-3-butenoate was reacted at 50°C. for 4 hours in 80 ml of methanol in the presence of 1.5g of calcium carbonate as a catalyst. In the same manner as in the preceding Examples, the resulting reaction mixture was neutralized and subjected to distillation under reduced pressure. Ethyl 4-cyclohexylidene-2-butenoate was obtained in a yield of 92% from a fraction boiling at 111 to 114°C. under 3 mm Hg.
