Reaktionsschritte
3-Hydroxybenzaldehyde (3 g, 24.6 mmol) and potassium carbonate (10.2 g, 73.8 mmol) were suspended in N,N-dimethylformamide (60 mL). 2-Picolyl chloride hydrochloride (4.44 g, 27.1 mmol) was added to this suspension, and stirred for 14 hours 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, and the residue was purified by silica gel column chromatography (heptane:ethyl acetate=4:1-2:1-1:1) to obtain the title compound (2.98 g, 57%).
