Ethylenediamine → N2-{5-[5-(1-methyl-1H-pyrazol-4-yl)-1H-pyrrolo[2,3-b]pyridin-3-yl]pyridin-3-yl}-N-(2,2,2-trifluoroethyl)valinamide

Reaction Steps

To a solution N2-{5-[5-(1-methyl-1H-pyrazol-4-yl)-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-pyrrolo[2,3-b]pyridin-3-yl]pyridin-3-yl}-N-(2,2,2-trifluoroethyl)valinamide 8-1a (190 mg, 0.316 mmol) from step 1 in DCM (2 mL) was added TFA (2.4 mL, 31.6 mmol) and the resultant mixture was stirred for 2 h. The mixture was concentrated in vacuo, resuspended in MeOH (1 mL) and to this was added ethylenediamine (0.043 mL, 0.632 mmol) and sodium hydroxide (10 M aq) (0.221 mL, 2.21 mmol). After 18 h, the reaction was transferred to vial with an additional 1 mL of dimethylsulfoxide and this solution was purified by mass triggered reverse phase HLPC. The fractions containing product 8-1 were basified with NaHCO3, dried over MgSO4, filtered and concentrated.
