実験手順

A mixture of 26.5 g of α-cyclopropyl-α-phenylbenzenemethanol and 150 ml of 48% HBr was stirred at ambient temperature for 3 h. After addition of ice water, the mixture was extracted twice with diethyl ether, washed, dried and concentrated to obtain 33 g (97.3%) of 4-bromo-1,1-diphenyl-1-butene.
