To a solution of t-butyl 6-(5-((tert-butyldimethylsilyloxy)methyl)thiazol-2-yl)pyridazin-3-yl((1-(3-fluoropyridin-2-yl)cyclobutyl)methyl)carbamate (112.5 g, 0.19 mol) in THF (1000 mL) was added TBAF (105 mL, 0.29 mol, 75% w/w). The reaction was stirred for 30 min followed by the addition of ammonium chloride (200 mL). The organic layer was separated, washed with brine (300 mL×3), and concentrated (this wash was repeated once). Ethyl acetate was added to the oil, resulting in a white solid. Filtration of the solid afforded 44 g of t-butyl (1-(3-fluoropyridin-2-yl)cyclobutyl)methyl(6-(5-(hydroxymethyl)thiazol-2-yl)pyridazin-3-yl)carbamate.
