Methanol → Methyl 2-(4-fluorophenyl)acetate

関与物質

反応手順

A catalytic amount (0.5 mL) of concentrated sulfuric acid was added to a solution of 4-fluorophenylacetic acid (30.8 g, 0.20 mol) in 500 mL of methanol. The solution was stirred at reflux for 4 hours. The volatile materials were removed under reduced pressure to furnish a colorless oil which was dissolved in ether/ethyl acetate and washed with 2 N aqueous Na2CO3, brine, dried over MgSO4, and filtered. The filtrate was concentrated under reduced pressure to provide an oil which was dried overnight under high vacuum (yield: 33.6 g; 95%). 1H NMR (300 MHz, CDCl3) δ 3.59 (s, 2H), 3.65 (s, 3H), 7.01 (t, J=9 Hz, 2H), 7.20-7.28 (m, 2H). MS (DCI/NH3) m/z 186 (M+NH4)+.
