실험 절차

To a stirring solution of tert-butyl (2-chloro-4-(3-((7-methoxy-1,5-naphthyridin-4-ylamino)methyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl)phenyl)methylcarbamate (70 mg, 128 μmol) in DCM (2 mL) was added TFA (2 mL). Reaction solution stirred for 30 min at 23° C. Solvents then removed under reduced pressure and residue purified on prep-HPLC using a water/ACN (0.1% TFA) gradient. Resulting solid was dissolved in 1:1 ACN/water (1 mL) and pH adjusted to 10 with 1M NaOH (approx 10 drops). Resulting solid collected by filtraton and washed with water (5 mL). MS (ESI pos. ion) m/z: 447 (MH+). Calc'd exact mass for C22H19ClN8O: 446.
