A mixture of compound 4 (1.50 g, 5.92 mmol), 3,6-dichloropyridazine (0.882 g, 5.92 mmol), bis(dibenzylideneacetone)palladium (0.170 g, 0.296 mmol), Xantphos (0.514 g, 0.888 mmol) and sodium tert-butoxide (0.854, 8.88 mmol) in toluene (80 mL) was purged with nitrogen. The reaction was then heated at 100° C. for one hour in a sealed vessel. After cooling to room temperature, the mixture was loaded onto a silica gel column and eluted with 2-10% methanol/DCM. Evaporation of combined fractions provided compound 140 (2.1 g) as a yellowish solid. LCMS-ESI, M+1: 366.1
