Reaction Steps
A solution of (RS)-(2,6-difluoro-3-hydroxy-phenyl)-ethoxy-acetic acid (14.8 g) in EtOH (200 ml) and 1.25 N HCl in EtOH (60 ml) was stirred over night at rt. The solvent was evaporated and the residue was purified by CC (AcOEt/Hept 1:1) to obtain 15.5 g (93%) of (RS)-(2,6-difluoro-3-hydroxy-phenyl)-ethoxy-acetic acid ethyl ester. Off-white solid. MS 258.9 ([M−H]−).
