Reaction Steps

A mixture of 6-(trans-4-aminocyclohexylamino)-N-(3-fluoropyridin-4-yl)-8-(N-(4-methoxybenzyl)methylsulfonamido)imidazo[1,2-b]pyridazine-3-carboxamide (30 mg, 0.037 mmol) in TFA (1 mL) was heated to 80° C. for 1.5 h. The reaction mixture was concentrated and evaporated from DCM/MeOH to give 20B (26 mg, 102%) as a white solid. [M+H]=463. HPLC Peak Rt=1.758 minutes. (Chromolith column 4.6×50 mm eluting with 10-90% aqueous methanol over 4 minutes containing 0.1% TFA, 4 mL/min, monitoring at 220 nm.)
