実験手順

Palladium on carbon (1:9, 23 mg, 0.022 mmol) is added to the product of step 4, Example 95A (235 mg, 0.308 mmol) in ethanol (5 mL) and water (1 mL). The mixture is evacuated with nitrogen three times and stirred under hydrogen for 5 hours. The reaction mixture is filtered through a 4 mL pad of solka flok and rinsed with alternating 4 mL rinses of ethanol and water ten times. The solvent is removed under reduced pressure to give the crude product, which is taken up in water (5 mL) and filtered through a 0.45 um filter disk, rinsing with water (2 mL). The filtrate is freeze dried to give the title product (126 mg): 1H NMR δ 8.75 (1H, s), 8.07 (1H, d), 7.63 (2H, d), 7.52-7.48 (4H, m), 6.00 (1H, t), 5.42 (1H, d), 4.82 (1H, dd), 4.64-4.43 (4H, m), 1.62 (3H, d); m/z: 447.12.
