Participants

Reaction Steps

Ethyl chloroformate (3.6 g) was added to 5-(4-benzylmorpholin-2-yl)methylidene-10,11-dihydro-5H-dibenzo[a,d]cycloheptene (3.13 g) in anhydrous benzene at room temperature, and the resulting mixture was heated under reflux for 5.5 hours. After cooling, the mixture was washed with a saturated aqueous sodium bicarbonate solution and water, dried and evaporated to afford 5-(4-ethoxycarbonylmorpholin-2-yl)methylidene-10,11-dihydro-5H-dibenzo[a,d]-cycloheptene as oily material.
