Reaction Steps

2-[5-Chloro-6-oxo-4-{[(1R,2R,3R,5S)-2,6,6-trimethylbicyclo[3.1.1]hept-3-yl]amino}pyridazin-1(6H)-yl]-N-[(3-hydroxypyridin-4-yl)methyl]acetamide (26.6 mg, 0.06 mmol) in tetrahydrofuran (1 mL) was mixed with 2-propanol (10.9 mg, 0.18 mmol), triphenylphosphine (23.6 mg, 0.09 mmol) and diethyl azodicarboxylate in toluene (2.2 M, 0.04 mL, 0.09 mmol) at 0° C. and stirred at room temperature for 4 hours. After completion of the reaction, the reaction solution was evaporated under reduced pressure, and the resulting residue was purified by silica gel chromatography (ethyl acetate/methanol 20/1) to give the desired product (4.48 mg, 15%).
