Reaction Steps

A suspension of methyl 4-(3-(4-(4-(8-oxa-3-azabicyclo[3.2.1]octan-3-yl)-1-(1,3-dimethoxypropan-2-yl)-1H-pyrazolo[3,4-d]pyrimidin-6-yl)phenyl)ureido)benzoate (25 mg) in tetrahydrofuran/methanol/water (2:2:1, 20 mL) was treated with two pellets of sodium hydroxide. The mixture was heated overnight at 60° C. and then acidified with concentrated hydrochloric acid to precipitate a fine solid, which, after collection via Buchner filtration, washing with water, and drying under house vacuum, provided 4-(3-(4-(4-(8-oxa-3-azabicyclo[3.2.1]octan-3-yl)-1-(1,3-dimethoxypropan-2-yl)-1H-pyrazolo[3,4-d]pyrimidin-6-yl)phenyl)ureido)benzoic acid.
