Reaction Steps

To a solution of 2-hydroxy-5-methoxybenzaldehyde (10 g, 65.7 mmoles) in 100 ml of sieve-dried dimethylformamide was added freshly-pulverized potassium carbonate (10 g, 72.3 mmoles) and undecyl bromide (15 ml, 67.3 mmoles). The reaction mixture was stirred at 100° C. for 1 hour, cooled to room temperature and then poured into ice-cold water/hexane. The layers were separated and the organic extract was washed with ice-cold 5% sodium hydroxide solution, water and saturated sodium chloride solution. The organic layer was dried with anhydrous magnesium sulfate, treated with charcoal and concentrated in vacuo. The resulting yellow solid was recrystallized from hexane, to give 16.2 g (80%) of the product as a white solid.
