To a solution of 42 g of the compound 10-keto-10,11-dihydro-dibenzo(b,f)-oxepine in 200 ml of dry ethanol a solution of sodiumethoxide (7 g of sodium in 500 ml of ethanol) is added dropwise. After stirring the mixture for 30 minutes 16.2 ml of methylvinylketon in 50 ml of ethanol are added, whereupon the solution is refluxed for 1 hour.
