実験手順
6-Chloro-4-(1-methyl-1H-pyrrolo[2,3-b]pyridin-6-ylamino)-pyridazine-3-carboxylic acid amide (42 mg, 0.139 mmol), and tert-butyl (1S,2R)-2-aminocyclohexylcarbamate (89 mg, 0.416 mmol) were dissolved in N-methylpyrrolidinone (1.4 mL) and heated at 150° C. for 36 h. Additional tert-butyl (1S,2R)-2-aminocyclohexylcarbamate (35 mg, 0.16 mmol) was added and the heating continued for 16 h more. The reaction mixture was cooled and concentrated in vacuo, then diluted with water, and extracted with ethyl acetate. The combined organic extracts were washed with brine, dried (sodium sulfate), filtered and concentrated in vacuo. Purification by chromatography (silica, 0 to 5% methanol in dichloromethane) gave {(1S,2R)-2-[6-carbamoyl-5-(1-methyl-1H-pyrrolo[2,3-b]pyridin-6-ylamino)-pyridazin-3-ylamino]-cyclohexyl}-carbamic acid tert-butyl ester (12 mg, 18%) as a light brown amorphous residue. LCMS (EI/CI) m/z: 481 [M+H].
