Methanol → Methyl 3-Hydroxyphenylacetate

Participants

Reaction Steps

A catalytic quantity of concentrated sulphuric add (1.0 ml) was added to a solution of (3-hydroxy)phenylacetic acid (17.38 g, 0.114tool) in methanol (100 ml). The reaction mixture was stirred for 3 hours at room temperature and then concentrated in vacuo. The residue was partitioned between diethyl ether (200 ml) and a saturated aqueous solution of sodium hydrogen carbonate (200 ml). The ether phase was separated and washed with non-saturated sodium hydrogen carbonate solution (200 ml) and saturated brine solution (100 ml). The ether extract was dried over magnesium sulphate. The solvent was evaporated and the residue dried to afford methyl 3-hydroxyphenylacetate as an amber oil (18.61 g, 98%); δH (360 MHz, CDCl3) 3.58 (2H, s, CH2), 3.70 (3H, s, COOCH3), 5.54 (1H, br s, OH), 6.74 (2H, m, ArH), 6.81 (1H, d, J 8 Hz, ArH), 7.17 (1H, t, J 8 Hz, ArH).
