Reaction Steps
The 4-hydroxy group of 4-hydroxybenzoic acid is protected by reacting 4-hydroxybenzoic acid, 5 g (0.036 mol), obtained commercially, with benzyl chloride, 5.1 g (0.04 mol) in ethanol:water (1:1) containing 5 g K2CO3 (0.04 mol) at a temperature of 30 degrees C. for 12 hours. The 4-PgO benzoic acid is converted to the acid chloride using thionyl chloride by a procedure similar to that employed for producing 3-cyclohexene carboxylic acid chloride from 3-cyclohexene carboxylic acid in Example I.
