Reaction Steps

To a solution of p-hydroxybenzoic acid, methyl ester (2.0 g, 13.2 mmol) in toluene/DMF (2:1) under argon was added NaH (630 mg, 2.0 eq.). After stirring for 15 minutes 3-phenylpropyl bromide (3.0 ml, 1.5 eq.) was added and the mixture refluxed for 4 hours. The solution was diluted with EtOAc and water. The organic layer was washed with H2O, 5% KHSO4 and brine, then dried over anhydrous MgSO4. Concentration in vacuo gave a yellow oil which solidified upon standing. Recrystallization from hexane/EtOAc gave title compound, a cream colored solid, 1.35 g (38%).
