Procedure

A mixture of tert-butyl (3-[2-(4-bromo-3-fluorophenyl)imidazo[1,2-b][1,2,4]triazin-7-yl]methylphenyl)carbamate (10 mg, 0.02 mmol) in trifluoroacetic acid (0.5 mL) and methylene chloride (0.5 mL) was stirred overnight at RT. The mixture was concentrated to afford the desired product as a TFA salt which was directly used for next step. LCMS: (M+H)=397.9/399.9.
