Methylamine → 3-(4-(6-fluoro-1-(phenylsulfonyl)-1H-indol-3-yl)-1H-pyrazol-1-yl)-N-methylazetidine-1-carboxamide

A mixture of CDI (62 mg; 0.38 mmol) and MeNH2 (0.20 ml; 0.40 mmol; 2.0 M in THF) of THF (10 mL) was stirred for 1 hour and added a premixed mixture of 3-(1-(azetidin-3-yl)-1H-pyrazol-4-yl)-6-fluoro-1-(phenylsulfonyl)-1H-indole hydrochloride (Intermediate 24; 200 mg; 0.46 mmol) and Et3N (0.10 ml; 0.72 mmol) in THF (2 mL) was stirred at rt for 10 min. The reaction mixture was stirred overnight and concentrated. The residue was diluted with EtOAc (50 mL), washed with water (20 mL), dried over anhydrous Na2SO4, filtered, and concentrated to afford 174 mg (100%) of the title compound as a yellow oil, which was used directly without further purification.
