Participants

Reaction Steps

2-{2-[5-Bromo-6-oxo-4-{[(1R,2R,3R,5S)-2,6,6-trimethylbicyclo[3.1.1]hept-3-yl]amino}pyridazin-1(6H)-yl]ethyl}-1H-isoindole-1,3(2H)-dione prepared above in methanol (6 mL) was stirred with hydrazine monohydrate (50 μL, 1.6 mmol) at 80° C. for 6 hours. After completion of the reaction, the solvent was removed by vacuum distillation, and the resulting residue was purified by silica gel column chromatography (ethyl acetate/methanol=4/1) to give the desired product (32 mg, 28% yield).
