Reaction Steps

6-Amino-5-methyl-4-(4-phenoxy-phenylamino)-pyrrolo[1,2-b]pyridazine-3-carbonitrile hydrochloride (10.3 mg, 0.026 mmol), benzeneboronic acid (4.7 mg, 0.039 mmol), Cu(OAc)2 (0.039 mmol, 7 mg) and TEA (0.13 mmol, 13 mg) in dichloromethane (1 ml) were stirred at RT for 16 hrs. The reaction mixture was purified by silica gel flash chromatography to isolate 370 as a yellow film (1.4 mg, 15%). [M+H]+=432.1.
