Reaction Steps

To a solution of 2-[5-(methanesulfonyl-(tert-butoxycarbonyl)-amino-methyl)-pyridin-3-yl]-1-methyl-indole (350 mg, 0.842 mmol) in dichloromethane (10 mL) is added chlorosulfonyl isocyanate (0.358 g, 2.53 mmol). The mixture is stirred at ambient temperature for 20 min, whereupon anhydrous DMF (2 mL) is added. After 1 h, the mixture is concentrated to a volume of 3 mL, and filtered. Purification by RP HPLC affords 2-[5-(methanesulfonyl-(tert-butoxycarbonyl)-amino-methyl)-pyridin-3-yl]-1-methyl-3-cyano-indole. MS (ESI) m/z 441.1 (M+H)+.
