Methylhydrazine → N,N-dicyclopropyl-7-[(1,5-dimethyl-1,2,4-triazol-3-yl)amino]-10-ethyl-3-methyl-3,5,8,10-tetrazatricyclo[7.3.0.02,6]dodeca-1,4,6,8,11-pentaene-11-carboxamide

Reaction Steps

A mixture of 4-(3-acetylthioureido)-N,N-dicyclopropyl-6-ethyl-1-methyl-1,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridine-7-carboxamide (example 125A, 17 mg, 0.039 mmol) and methylhydrazine (2.486 μL, 0.046 mmol) in acetic acid (0.5 mL) was heated at 80° C. for 4 h, LC/MS showed starting material still remaining. Additional methylhydrazine (2.486 μL, 0.046 mmol) was added and heating continued for another 2 h, reaction complete. Solvent was evaporated and the crude was purified by preparative HPLC to furnish N,N-dicyclopropyl-4-(1,5-dimethyl-1H-1,2,4-triazol-3-ylamino)-6-ethyl-1-methyl-1,6-dihydroimidazo[4,5-d]pyrrolo[2,3-b]pyridine-7-carboxamide (5.2 mg, 30.7% yield) as an off-white solid.
