Reaction Steps
To a stirred solution of ethyl 2-(4-hydroxyphenyl)acetate (20 g, 0.076 molo) in 200 ml of DCM was added MeOH (3.4 ml, 0.84 mol). The mixture was brought to reflux and sulfuryl chloride (6.8 ml 0.846 mol) dissolved in DCM (50 mL) was slowly added under over 10 min. The reaction mixture was refluxed further for 5 h, upon which the reaction mixture was poured onto crushed ice and extracted with DCM (×2). The combined organic layers were washed with 10% NaHCO3 solution and water. The organic layer was dried over Na2SO4, filtered and evaporated under vacuum to give compound ethyl 2-(3-chloro-4-hydroxyphenyl)acetate in 60% yield. (13.6 g).
