Procedure
To a flask containing (4-chloro-2-methoxy-3-(4-(trifluoromethyl)benzyl)quinolin-6-yl)(3,5-dimethylisoxazol-4-yl)methanol (1.4 g, 2.94 mmol, Intermediate 63: step a) was added THF (75 mL) followed by manganese dioxide (1.1 g, 12.6 mmol). The reaction mixture was heated to reflux for 2 hours, and then the contents were filtered through Celite® and rinsed with additional THF. The effluent was concentrated to provide the title compound as a white amorphous solid which was used without further purification.
