Reaction Steps

A 20-mL microwave vial was charged with 2-(4-(4-((6-chloro-5-fluoro-3-pyridinyl)sulfonyl)-2-(1-propyn-1-yl)-1-piperazinyl)phenyl)-1,1,1,3,3,3-hexafluoro-2-propanol (165 mg, 0.30 mmol), aq. ammonium hydroxide (3 mL, 30% solution, 15.4 mmol, J. T. Baker, Phillipsburg, N.J.) and EtOH (3 mL). The is reaction vessel was sealed and the mixture heated to 150° C. overnight. The reaction was diluted with water (50 mL) and extracted with EtOAc (3×100 mL). The combined organics were dried (Na2SO4), filtered, and concentrated to give an oil that was purified via column chromatography on silica gel (0-10% MeOH in CH2Cl2) to give 2-(4-(4-((6-amino-5-fluoro-3-pyridinyl)sulfonyl)-2-(1-propyn-1-yl)-1-piperazinyl)phenyl)-1,1,1,3,3,3-hexafluoro-2-propanol (60 mg) as a mixture of two isomers.
