実験手順

The solution of 3-hydroxy-2-methoxybenzaldehyde (5.06 g, 32.7 mmol), 2,6-Dimethylbenzyl chloride (5.04 g, 33.1 mmol) and K2CO3 (4.78 g, 34.6 mmol) in dry DMF (15 ml) was stirred at room temperature under argon for 16 hours, then diluted with EtOAc (40 ml), and washed with water (20 ml). The organic layer was concentrated, and purified by flash chromatography on a silica gel column (hex: ethyl acetate 4:1) to give the title compound as an off white solid.
