Reaction Steps
To a solution of 4-hydoxybenzaldehyde (4.0 g, 32.8 mmol) in dry DMF (100 mL) was added 2-bromopropane (6.0 g, 49.2 mmol) and potassium carbonate (6.8 g, 49.2 mmol). The resulting reaction was heated to 100° C. and stirred for 3 hours. The reaction was quenched by adding excess water and partitioned between ethyl acetate and brine. The organic layer was washed with brine, dried (Na2SO4), filtered, and concentrated under vacuum. Purification on silica gel with 15% ether/hexane afforded the title compound (5.0 g, 93%).
