N-bromobutanimide → 2-(4-(1-(Pyrazolo[1,5-a]pyridin-5-ylmethyl)-1H-[1,2,3]triazolo[4,5-b]pyrazin-6-yl)-1H-pyrazol-1-yl)ethanol

To a solution of 1-(pyrazolo[1,5-a]pyridin-5-ylmethyl)-6-(1-(2-(tetrahydro-2H-pyran-2-yloxy)ethyl)-1H-pyrazol-4-yl)-1H-[1,2,3]triazolo[4,5-b]pyrazine 311-a (10 mg, 0.022 mmol) (prepared according to the procedure of Compound 1) in CHCl3 was added NBS (4.4 mg, 0.025 mmol). The reaction mixture was stirred at rt for 1 h, then concentrated. The resulting residue was dissolved in CHCl3 (2 mL) and MeOH (2 mL), followed by the addition of 6N HCl in MeOH. The resulting mixture was stirred for 30 min, then treated with NH3.H2O to bring pH to 8. The mixture was concentrated and purified by prep-TLC to afford the title compound. MS (m/z): 439.9 (M+1)+.
