Reaction Steps

A solution of 1-{3,5-difluoro-4-[(phenylmethyl)oxy]phenyl}-4-hydroxy-1H-indazole-6-carbonitrile (D37) (610 mg, 1.617 mmol) in ethyl acetate (50 mL) was passed through the H-cube over a 10% palladium on charcoal catalyst at room temperature and pressure. The filtrate was concentrated and then triturated with dichloromethane and collected by filtration to yield the desired product (E20) (235 mg).
