Versuchsvorschrift

To a suspension of Example 394 (40 mg, 0.088 mmol) in MeOH (15 mL) was added triethylamine (0.040 mL, 0.263 mmol) and 5% Pd/C (10 mg, 25% wt). The reaction mixture was stirred under an atmosphere of hydrogen for 24 h, then the catalyst was filtered off and the filtrate was concentrated in vacuo. The residue was partitioned between DCM (50 mL) and water (50 mL); the organic phase was washed with brine (50 mL), dried (MgSO4), and concentrated in vacuo to give the title compound (24 mg, 65%) as an off-white solid. δH (CDCl3) 8.45 (1H, d, J 5.8 Hz), 7.97 (1H, d, J 2.6 Hz), 6.98 (1H, d, J 8.9 Hz), 6.84 (1H, dd, J 8.9 and 2.6 Hz), 6.63 (1H, d, J 5.8 Hz), 5.58 (1H, s), 4.41-4.26 (2H, m), 4.16-4.05 (2H, m), 2.84 (2H, s), 2.62 (3H, s), 1.37 (6H, s). LCMS (ES+) 424.0 (M+H)+, RT 2.75 minutes (Method 1).
