Reaction Conditions:
with potassium carbonate in N,N-dimethyl-formamide at 20; for 12 h;
Steps:
4.1.1. General Procedure for the Preparation of Compounds 1a-18a
General procedure: A solution of 4-hydroxybenzaldehyde (1 g, 8.2 mmol), substituted benzyl bromide(8.4 mmol, 1.02 eq) and potassium carbonate (1.7 g, 12.3 mmol) in 30 mL of N,N-dimethylformamide (DMF) was stirred overnight under an inert atmosphere at room temperature[29]. Subsequently, 50 mL water was added and the mixture was extracted with ethylacetate (40 mL 3). The combined organic phase was washed with a saturated brine (30 mL 2), dried over anhydrous MgSO4, filtered, and concentrated under reduced pressureto give the crude product, which was purified by column chromatography on silicagel (10-50% ethyl acetate in petroleum ether) to obtain the corresponding products, 1a-18a.(2-((4-Formylphenoxy)methyl)phenyl)boronic acid (1a).
