Reaction Steps
A solution of 1-{3,5-difluoro-4-[(phenylmethyl)oxy]phenyl}-4-[(phenylmethyl)oxy]-1H-indazole (D35) (257 mg, 0.58 mmol) in ethanol (10 mL) and ethyl acetate (10 mL) was hydrogenated in an H-cube over a 10% palladium on charcoal catalyst. The resulting solution was concentrated and then the crude product purified by silica gel chromatography eluting with 5-100% ethyl acetate in hexane to yield the title compound (E19) (126 mg).
