Reaction Steps

83B (19 mg, 0.029 mmol) was dissolved in MeOH (1 mL). 0.5 mL of 1N NaOH was added, and the cloudy reaction mixture was stirred at 65° C. After 2 hrs, the reaction mixture was cooled to room temperature, the pH adjusted to pH 7 with 1N HCl, and the solid was collected via Buchner filtration to afford 6-((trans)-4-(tert-butoxycarbonylamino)cyclohexylamino)-8-(cyclopropyl(4-methoxybenzyl)amino)imidazo[1,2-b]pyridazine-3-carboxylic acid as a white solid (10.6 mg, 0.019 mmol, 65.3% yield). LC/MS (Phenomenex Luna 5 micron C18 4.6×30 mm, 0 to 100 B in 2 min with 1 min hold time, Flow rate=5 mL/min, detection at 254 nm, Solvent A: 10% methanol/90% water/0.1% TFA; Solvent B: 10% water/90% methanol/0.1% TFA) Rt=2.1 minutes. [M+H]=551.36.
