Reaction Steps

To a 100 mL round bottom flask was added t-butyl (1-(3-fluoropyridin-2-yl)cyclobutyl)methyl(6-(thiazol-2-yl)pyridazin-3-yl)carbamate (2.0 g, 4.6 mmol), NBS (1.6 g, 9.1 mmol), and DMF (20 mL). The reaction was heated to 100° C. and stirred overnight. The reaction mixture was then was poured into ethyl acetate (200 mL), washed with water (100 mL), dried over Na2SO4, filtered, concentrated, and purified by silica gel chromatography (EtOAc/hex) to afford 1.8 g of t-butyl 6-(5-bromothiazol-2-yl)pyridazin-3-yl((1-(3-fluoropyridin-2-yl)cyclobutyl)methyl)carbamate.
