実験手順

To an N,N-dimethylformamide (250 mL) solution of 4-hydroxybenzaldehyde (20 g, 164 mmol) and 2-picolyl chloride (27 g, 165 mmol) was added potassium carbonate (68 g, 492 mmol), which was stirred for 3 days at room temperature. This mixture was partitioned into ethyl acetate and water. The organic layer was separated, washed with water, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated under a reduced pressure to obtain the title compound (29 g, 83%). The title compound was not purified but used for the next reaction.
