Reaction Conditions

Reaction Steps

To a solution of DMF (50 mL) was added 1-bromo-2-nitro-4-chloro-benzene (10.0 g, 42.2 mmol), 3-hydroxybenzaldehyde (5.2 g, 42.2 mmol), and K2CO3 (11.5 g, 84.6 mmol). The solution was heated to 85° C. and stirred overnight. The reaction was poured into distill water and extracted with ethyl acetate. The combined organic layers were washed with distilled water, brine, and dried over Na2SO4, filtered and concentrated under vacuum giving the crude title compound. This solid was purified by silica gel column chromatography eluting with hexanes/ethyl acetate (4:1) to give the title compound (4.4 gm, 41%).
