HCID 109117821-Bromo-4-(1,1-dimethoxyethyl)benzene

Procedure

A mixture of 2 g (0.01 mole) of 4-bromoacetophenone, 5.6 ml of trimethyl orthoformate, 5.6 ml of methanol and 0.67 g of Amberlite® IR 120 is heated at reflux for 3 hours. After cooling, the mixture is filtered through Celite® and the filtered solution is evaporated. 2.4 g of the title compound are obtained in the form of an oil.
