Procedure

Pd(OH)2 (1 g) and compound 9 (9.26 g, 0.030 mol) in MeOH (200 mL) were stirred under hydrogen at 20-30 psi pressure for 16-18 hours. The mixture was then filtered through Celite®, and the filtrate was concentrated to give compound 10 as a white solid. 1H NMR (DMSO-d6; 400 MHz) δ 9.16 (s), δ 7.16 (d), δ 7.00 (m), δ 6.65 (m), δ 4.71 (t), δ 3.62 (d), δ 1.27 (s), δ 1.22 (s).
