Reaction Steps

A scintillation vial was charged with (5-(4-(4-(7-methoxy-1,5-naphthyridin-4-yloxy)phenylamino)phthalazin-1-yl)thiophen-3-yl)methyl acetate (137 mg, 249 μmol), 1.0 mL 3:1:1 THF:MeOH:water and lithium hydroxide (47.8 mg, 1994 μmol). The homogeneous mixture was stirred at RT for 2 h. Water was added to the mixture, and the precipitated solids were filtered, washed with water, and dried. The crude solids were purified by reverse phase chromatography, Gilson, 10-90% 0.1% TFA/ACN in water to provide (5-(4-(4-(7-methoxy-1,5-naphthyridin-4-yloxy)phenylamino)phthalazin-1-yl)thiophen-3-yl)methanol. MS: [M+H]=508.
