Reaction Steps

To a 20 dram vial was added 2-fluoro-5-(6-((1-(3-fluoropyridin-2-yl)cyclobutyl)methylamino)pyridazin-3-yl)benzoic acid (320 mg, 0.8 mmol, 1.0 equiv), benzyl 2-aminoethylcarbamate (242 mg, 1.0 mmol, 1.3 equiv), HOBt (141 mg, 1.0 mmol, 1.3 equiv), EDC HCl (200 mg, 1.0 mmol, 1.3 equiv), DIPEA (550 μL, 3.8 equiv) and CH2Cl2 (5 mL). The reaction was stirred for 4 h and then concentrated and then purified using a silica gel column (50%-100% EtOAc/hexanes) to afford 230 mg (50%) of benzyl 2-(2-fluoro-5-(6-((1-(3-fluoropyridin-2-yl)cyclobutyl)methylamino)pyridazin-3-yl)benzamido)ethylcarbamate as a white foam.
