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]-N-(pyridin-4-ylmethyl)acetamide (100 mg, 0.21 mmol) in N-methylpyrrolidone (2.5 mL) was mixed with copper cyanide (100 mg, 1.05 mmol) at room temperature and stirred at 110° C. for 24 hours. After completion of the reaction, the reaction solution was mixed with water and extracted with ethyl acetate and chloroform. The extract was dried over anhydrous magnesium sulfate and evaporated under reduced pressure. The resulting residue was purified by silica gel column chromatography (chloroform/methanol=10/1) to give the desired product (4.3 mg, 5% yield).
