Procedure

Compound 12 (505 mg, 1.00 mmol) was dissolved in methanol (20 mL) and 10% palladium on carbon (100 mg) was added. The flask was evacuated, filled with hydrogen gas under balloon pressure and stirred overnight. Filtration through celite to remove the catalyst followed by removal of the solvent under reduced pressure provided compound 13 (366 mg, 98%). 1H NMR (300 MHz, CDCl3) δ 7.08 (d, 2H), 6.80 (d, 2H), 5.51 (d, 1H), 4.66 (m, 1H), 4.38 (m, 1H), 4.17 (m, 1H), 3.78 (s, 3H), 2.73 (m, 2H), 2.58 (m, 2H), 1.90 (br s, 2H), 1.62 (m, 2H), 1.50 (m, 2H), 1.48 (s, 9H).
