الإجراء التجريبي

To a stirring solution of (7-chloro-6-((2R,6S)-2,6-dimethylmorpholino)-3-(pyridin-2-yl)isoxazolo[4,5-b]pyridin-5-yl)methanol (Intermediate 201, 0.39 g, 1.04 mmol) in dichloromethane (20 mL) was added Manganese dioxode (0.543 g, 6.24 mmol). The mixture was allowed to stir 2 days at room temperature. The reaction was filtered over Celite®, and the filtrate concentrated under vacuum to give clear oil. The oil was purified on short bed of silica using 20-30% acetone in n-hexane to give 0.16 g (42%) of the title compound as a yellow solid.
