25.00 g of benzyl phenyl ketone was mixed with 92 ml of N,N-dimethylformamide dimethyl acetal and then heated at reflux for one hour. Almost all of N,N-dimethylformamide dimethyl acetal was evaporated under reduced pressure and the deposited crystal was washed with diethyl ether. After drying, 31.40 g of the desired compound was obtained as a pale yellow crystal having a melting point of 128 to 130° C.
