Reaction Steps

To a stirred solution of 2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (100 mg, 0.32 mmol) in 6 mL of DMF was added EDCI (123 mmol, 0.64 mmol), DMAP (110 mg, 0.90 mmol) and tert-butyl 4-amino-4-methylpentylcarbamate (139 mg, 0.64 mmol) in one portion at room temperature and the mixture stirred at room temperature for 16 hours. The reaction mixture was poured into 40 mL of water, filtered, the filter cake washed with petroleum ether then dried to give crude tert-butyl 4-(2-(6-fluoro-1-methyl-1H-indazol-3-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamido)-4-methylpentylcarbamate (75 mg, 46%) as a yellow solid. MS: (M+H)+=510.2.
