To a solution of Intermediate 22 (220 mg, 1.29 mmol) in methanol (8 mL) is added Amberlyst-15 resin (50 mg) and the mixture is stirred at room temperature for 18 hrs. The resin is filtered and the solvent is removed under reduced pressure to give the product which is used as is in subsequent reactions. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 3.75 (s, 3H), 3.82 (s, 2H), 6.45 (d, J=3.54 Hz, 1H), 7.29 (d, J=3.54 Hz, 1H), 10.17 (s, broad, 1H).
