Reaction Steps

A mixture of methyl p-hydroxybenzoate (4.38 g, 28.8 mmol), p-fluorobenzyl chloride (5.0 g, 34.6 mmol) and anhydrous potassium carbonate (10 g) in acetone (250 ml) was heated under reflux for 24 h. The solid was then filtered and the filtrate was evaporated under reduced pressure. Crystallization of the residue from hexane gave 7.20 g (96%) of the title ester as white plates: mp 93-94° C. 1HNMR 400 MHz (CDCl3) δ (ppm): 3.9 (3H, s, OCH3), 5.1 (2H, s, CH2), 7.0 (2H, d, J=8.8 Hz, aromatics), 7.11 (2H, m, aromatics), 7.43 (2 H, m, aromatics), 8.02 (2H, d, J=8.8 Hz, aromatics). Anal. Calcd for C15H13FO3: C, 69.22; H, 5.03. Found: C, 68.89; H, 4.69.
