Reaction Steps
To a solution of 3-hydroxybenzaldehyde (2.0 g, 16.38 mmol) in DMF (25 mL) was added NaH (60%, 982.6 mg, 24.57 mmol) at 0° C. in portions. The mixture was stirred at this temperature for 30 minutes before a solution of 2-(chloromethyl)oxirane (2.27 g, 24.57 mmol) in DMF (5 mL) was slowly added into the reaction mixture which was then allowed to reach room temperature slowly and stirred for 16 h. The solvent was removed by concentration and the residue dissolved in ethyl acetate and washed with water. T the separated organic layer was dried over sodium sulfate, filtered and concentrated. The crude product was then purified by column chromatography. (2.2 g, yield 75%) MS (ESI+) e/z: 179.1 [M+1]+.
