Reaction Steps
To a solid of 2-(1H-benzo[d][1,2,3]triazol-1-yloxy)-4-(1-methyl-1H-indol-4-ylamino)pyrimidine-5-carboxamide (100 mg, 0.25 mmol) in vial was added tert butyl (1S, 2R)-2-aminocyclohexylcarbamate (0.3 M solution in NMP, 1.25 mL, 0.375 mmol) and DIPEA (0.09 mL, 0.5 mmol). It was heated at 80° C. for 2 h, cooled and purified by preparative HPLC to give 2-((1R,2S)-2-aminocyclohexylamino)-4-(1-methyl-1H-indol-4-ylamino)pyrimidine-5-carboxamide (21 mg). MS found for C20H25N7O as (M+H)+ 380.4. UV: λ=219.2, 241.6, 336.7.
