実験手順: A 250 mL, three-neck, round bottomed flask equipped with a magnetic stirrer was purged with nitrogen and charged with tert-butyldimethylsilyl chloride (12.5 g, 82.8 mmol), imidazole (7.64 g, 112 mmol), and anhydrous DMF (60 mL). 3-aminophenol (10.0 g, 91.7 mmol) was added to the resulting solution. After stirring for 12 h at ambient temperature, the reaction mixture was poured into water (300 mL). The resulting suspension was extracted with hexanes (3×300 mL), and the extracts were combined, dried over sodium sulfate, and filtered. Concentration of the filtrate followed by column chromatography gave compound 122 as a light yellow oil. 1H NMR (DMSO-d6) δ (ppm), 6.84 (t, 1H, J=7.9 Hz), 6.16 (d, 1H, J=6.7 Hz), 6.10 (m, 1H), 5.97 (d, 1H, J=9.1 Hz), 4.98 (s, 2H), 0.95 (s, 9H), 0.16 (s, 6H); m/z=224 (M+H). A 250 mL, three-neck, round bottomed flask equipped with a magnetic stirrer was purged with nitrogen The resulting suspension was extracted with hexanes (3×300 mL) dried over sodium sulfate filtered
