Reaction Steps

A solution of compound 58 (80 mg, 0.18 mmol) in EtOAc (5 mL) was added Pd/C (10 mg, 10%) under N2. The suspension was degassed under vacuum and purged with H2 several times. The mixture was stirred under H2 balloon at room temperature for 2 h. The suspension was filtered and the solid was washed by EtOAc. The filtrates were concentrated to dryness to give compound 59 (38 mg, 70%) as a light yellow oil. The crude product was used directly for the next step without purification. 1H NMR (400 MHz, CDCl3) δ7.32-7.43 (m, 1H), 6.96-7.02 (m, 3H), 6.93 (d, 2H, J=8.3 Hz), 3.17 (t, 2H, J=7.4 Hz), 2.66 (t, 2H, J=7.4 Hz), 2.05-2.13 (m, 2H), 1.62 (s, 9H).
