Reaktionsschritte

A solution of 4-fluoro-3-methylphenol (3.0 g, 23 mmol) and methylene chloride (96 mL) was cooled to 0° C. in an ice bath. Triethylamine (4.9 mL, 35 mmol) was introduced to the solution followed by dropwise addition of acetyl chloride (2.3 mL, 33 mmol). The ice bath was removed and the mixture was stirred for 1 hour. The mixture was then extracted with methylene chloride and washed with 0.5 N HCl, saturated sodium bicarbonate and brine. The extracts were dried over sodium sulfate, filtered and evaporated to give 4-fluoro-3-methylphenyl acetate (3.9 g, quantitative). 1H NMR (400 MHz, CDCl3): δ 7.00 (m, 1H), 6.87 (m, 2H), 2.29 (m, 6H).
