実験手順

To a solution of tert-butyl 3-((4-(6-fluoro-1-(phenylsulfonyl)-1H-indol-3-yl)-1H-pyrazol-1-yl)methyl)azetidine-1-carboxylate (Intermediate 37; 330 mg; 0.65 mmol) in DCM (10 mL) was added TFA (5 mL) dropwise. The reaction mixture was stirred for 0.5 hour and concentrated, neutralized with saturated aqueous Na2CO3 (50 mL), extracted with EtOAc (50 ml×2). The combined organic layers were dried over anhydrous Na2SO4, filtered, concentrated and purified by preparative TLC to afford 265 mg (100%) of the title compound as a brown solid.
