Reaction Steps
To a solution of methyl 6-isocyanatopyridazine-3-carboxylate (5.26 g, 29.4 mmol) in THF (100 mL), a solution of isoindoline (5.24 g, 4.41 mmol) in THF (50 mL) was added at 0° C. The reaction mixture was stirred overnight at room temperature. The reaction mixture was filtered and the precipitate was washed with cold EtOAc and dried in high vacuum to give the title compound as a solid.
