Procedure
To a stirring solution of methyl 3,5-dimethyl-4-(4′-methoxymethoxy-3′-iso-propylbenzyl)benzoate (0.750 g, 2.11 mmol) in MeOH (20.0 mL) at 0° C. was added 1 M NaOH (12.64 mL, 12.64 mmol). The reaction mixture was heated at 50° C. for 16 h, cooled to 0° C. and acidified with 2 N HCl. The mixture was extracted with ethyl acetate (20 mL) and washed with H2O (10 mL×2.). The solvent was removed under reduced pressure to afford 3,5-dimethyl-4-(4′-methoxymethoxy-3′-iso-propylbenzyl)benzoic acid as white solid (0.71 g, 98%): 1H NMR (300 MHz, DMSO-d6): δ 12.76 (s, 1 H), 7.65 (s, 2 H), 6.98 (m, 1 H), 6.91 (m, 1 H), 6.60 (m, 1 H), 5.17 (s, 2 H), 4.00 (s, 2 H), 3.37 (s, 3 H), 3.23 (m, 1 H), 2.27 (s, 6 H), 1.14 (d, J=6.0 Hz, 6 H); TLC conditions: Uniplate silica gel, 250 microns; Mobile phase=hexanes-ethyl acetate (4:1); Rf=0.00.
