実験手順
To the title compound from Example 1 Step A (0.267 g, 1.57 mmol) were added palladium on carbon (0.027 g) and methanol (7.85 mL). The resulting mixture was stirred under an atmosphere of hydrogen at room temperature overnight. The mixture was then filtered through CELITE® using dichloromethane, and the filtrate was concentrated. Purification by flash chromatography (50% ethyl acetate in hexanes, then 100% ethyl acetate) provided the title compound: 1H NMR (500 MHz, CDCl3) δ 6.61 (dd, J=8.2, 5.6 Hz, 1 H), 6.36-6.30 (m, 2 H), 3.22 (br s, 3 H), 2.84 (s, 3 H).
