To a stirring solution of afford methyl 3,5-dimethyl-4-[3′-(4-fluorobenzyl)-4′-methoxymethoxybenzyl]benzoate (compound 78, step f, 2.8 g, 6.63 mmol) in MeOH (80 mL) at 0° C. was added NaOH (27 mL, 1 N). After heating at 50° C. for 16 h, the solvent was removed under reduced pressure and the residue was acidified with 1 N HCl to pH=1, and the mixture was extracted with EtOAc. The organic layer was dried over Na2SO4, filtered and concentrated under reduced pressure to afford 3,5-dimethyl-4-[3′-(4-fluorobenzyl)-4′-methoxymethoxybenzyl]benzoic acid as white solid (2.7 g, 100%): 1H NMR (300 MHz, DMSO-d6): 12.71 (s, 1H), 7.64 (s, 2H), 7.01-7.22 (m, 4H), 6.95 (d, J=8.4 Hz, 1H), 6.85 (d, J=2.1 Hz, 1H), 6.73 (dd, J=2.1, 8.4 Hz, 1H), 5.15 (s, 2H), 3.98 (s, 2H), 3.86 (s, 2H), 3.27 (s, 3H), 2.25 (s, 6H).
