実験手順

6-Amino-5-methyl-4-(4-phenoxy-phenylamino)-pyrrolo[1,2-b]pyridazine-3-carbonitrile hydrochloride (10.4 mg, 0.027 mmol), 2-acetylamino benzoic acid (7 mg, 0.04 mmol), PyBOP (21 mg, 0.04 mmol) and DIEA (8.6 mg, 0.067 mmol) in 1.2-dichloroethane (0.5 ml) were stirred at RT for 16 hrs. The reaction mixture was concentrated and purified by silica gel flash chromatography to isolate 375 as a yellow film (5.8 mg, 42%). [M+H]+=498.
