To a solution of 1-[3-(tert-butyl-dimethyl-silanyloxymethyl)-4-methoxy-phenyl]-cyclopropanecarboxylic acid methyl ester (6.2 g, 18 mmol) in MeOH (75 mL) was added a solution of LiOH.H2O (1.50 g, 35.7 mmol) in water (10 mL) at 0° C. The reaction mixture was stirred overnight at 40° C. MeOH was removed by evaporation under vacuum. AcOH (1 mol/L, 40 mL) and EtOAc (200 mL) were added. The organic layer was separated, washed with brine, dried over anhydrous Na2SO4 and evaporated under vacuum to provide 1-(3-hydroxymethyl-4-methoxy-phenyl)-cyclopropanecarboxylic acid (5.3 g).
