실험 절차

2-(1-isopropyl-3-methyl-1H-1,2,4-triazol-5-yl)-9-vinyl-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine from Example 447 (0.300 g, 0.894 mmol) was dissolved in ethanol (5 mL) and purged with N2. 10% Palladium on Carbon (0.1:0.9, Palladium:carbon black, 0.0952 g) was added. The resulting suspension was placed under vacuum followed by addition of H2 at atm pressure. This process was repeated three times to saturate the catalyst. The reaction was stirred for 18 hours at room temperature. The reaction mixture was filtered and concentrated to dryness. The crude product was purified using reverse phase chromatography to give 499 (0.189 g, 62.9% yield).
