Procedure
To the solution of 2-(4-(6-fluoro-1-(phenylsulfonyl)-1H-indol-3-yl)-1H-pyrazol-1-yl)ethanamine hydrochloride (Intermediate 19; 228 mg; 0.54 mmol) and DMAP (3 mg; 0.02 mmol) in pyridine (4 mL), was added MsCl (0.07 mL; 0.90 mmol) under nitrogen at 0° C. The reaction was warmed to r.t. and stirred overnight. The reaction mixture was concentrated and the residue was diluted with EtOAc (20 mL), washed with aqueous HCl (10 mL; 1 M), water (10 mL), brine (10 mL). The organic layer was dried over anhydrous Na2SO4, filtered, and concentrated to afford 300 mg of the title compound as a yellow solid, which was used directly without further purification.
