Reaction Steps

To a solution of 4-benzyloxy-3-hydroxybenzaldehyde (5 g, 21.9 mmol) in DMF (50 mL) was added cyclopentyl bromide (4.7 mL, 43.8 mmol) and K2CO3 (12.1 g, 87.6 mmol). The reaction mixture was stirred at r.t. overnight. K2CO3 was then filtered from the mixture. The mixture was extracted with EtOAc, and the organic layer was washed with water (2×) and then brine, and finally dried over Na2SO4. The product was concentrated under reduced pressure and purified by silica gel to provide a colorless oil which solidified to a white solid upon standing. Yield: 98%.
