Reaction Steps

To a solution of compound 412 (90 mg, 0.22 mmol) in methanol (5 mL) was added Pd/C (10% wt, dry basis) (50 mg). The reaction was stirred at room temperature with H2 ballon for 3 hours. Insolubles were removed by filtration. The filtrate was purified using prep-HPLC to give compound 413 as a yellow solid (30 mg, 33%). 1H NMR (500 MHz, DMSO-d6) δ ppm 10.98 (1 H, br. s.), 9.64 (1 H, s), 9.42 (1 H, s), 8.83 (1 H, dd, J=3.5, 1.1 Hz), 8.71 (1 H, d, J=6.1 Hz), 8.55-8.68 (2 H, m), 8.30 (1 H, d, J=2.7 Hz), 8.17 (1 H, d, J=8.6 Hz), 7.85 (1 H, dd, J=8.8, 2.4 Hz), 5.41 (1 H, dq, J=8.9, 8.8 Hz), 3.43 (2 H, dd, J=10.4, 2.3 Hz), 2.96 (3 H, tt, J=12.1, 3.7 Hz), 2.42 (2 H, m), 2.00-2.08 (4 H, m), 1.68-1.92 (2H, m); LCMS-ESI (POS), M/Z, M+1: Found 414.2, Calculated 414.2.
