Methanol → Methyl 2-(2-fluoro-5-nitrophenyl)acetate

Participants

Reaction Steps

To a solution of 2-(2-fluoro-5-nitrophenyl)acetic acid (1.0 g, 5.0 mmol) in CH3OH (20 mL) was added con. H2SO4 (0.50 mL), the reaction was warmed to 80° C. and stirred for about 3 hr. After cooling down to RT, the reaction was poured into water (20 mL) and concentrated to remove CH3OH. The aqueous was extracted with ethyl acetate (2×20 mL), the combined organic phases were washed brine (10 mL), dried over Na2SO4, filtered and concentrated to afford the product about 1.0 g (93.4%) as a colorless oil. MS (ESI) m/e [M+1]+ 214.0.
