実験手順

To a stirred solution of 2-(6-methyl-1H-indazol-3-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxylic acid (100 mg, 0.34 mmol), EDCI (130 mmol, 0.68 mmol), DMAP (83 mg, 0.68 mmol) and DIEA (88 mg, 0.68 mmol) in 6 mL of DMF was added tert-butyl 2-amino-2-methylpropylcarbamate (128 mg, 0.68 mmol) in one portion at room temperature, then the mixture was stirred for 16 hours. The reaction mixture was poured into 40 mL of water, filtered and the filter cake was washed with petroleum ether to give crude tert-butyl 2-methyl-2-(2-(6-methyl-1H-indazol-3-yl)-5H-pyrrolo[2,3-b]pyrazine-7-carboxamido)propylcarbamate (100 mg, 63.4%) as a pale yellow solid. MS: (M+H)+=463.2.
