실험 절차
A solution of 28 (304 mg, 1 mmol) in EtOAc (20 mL) was hydrogenated at 60 psi in the presence of 10% Pd-C (60 mg) for 12 h. The solution was filtered, and solvents were evaporated. The crude product was purified by crystallization from EtOAc and hexane (183 mg, 60%); mp 66°-67° C.; 1H NMR (CDCl3, 200 MHz) δ7.12 (d, J=8.5 Hz, 2H), 6.85 (d, J=8.5 Hz, 2H), 6.39 (s, 2H), 3.87 (s, 2H), 3.82 (s, 3H), 3.81 (s, 6H), 3.79 (s, 3H); CIMS (isobutane) m/e 289 (MH+, 100). Anal. (C17H20O4) C, H.
