Participants

Reaction Steps

A DMF (4 mL) solution containing Na2CO3 (60 mg, 0.57 mmol), 4-chloro-2-fluoro-1-nitrobenzene (100 mg, 0.57 mmol) and methyl 4-hydroxybenzoate (87 mg, 0.57 mmol) was stirred at room temperature for 8 hours. HPLC analysis indicated ca. 85% product. The reaction solution was stirred for an additional 2 hours at 40° C. The solution was then diluted with ethyl acetate and washed with 1N NaOH. The organic phase was washed with water (3×), brine and dried over Na2SO4. The solution was filtered, concentrated and the residue purified by silica gel chromatography using a hexanes/ethyl acetate gradient to give the title compound. 1H NMR (500 MHz, CDCl3): δ 8.11 (d, J=8.1 Hz, 2H); 8.01 (d, J=8.2 Hz, 1H); 7.31-7.27 (m, 1H); 7.11-7.07 (m, 3H); 3.95 (s, 3H). LCMS1 3.66 min. (M+H)=308.
