Procedure
t-Butyl (3S)-3-[({[5-bromo-6-oxo-4-{[(1R,2R,3R,5S)-2,6,6-trimethylbicyclo[3.1.1]hept-3-yl]amino}pyridazin-1(6H)-yl]acetyl}amino)methyl]pyrrolidine-1-carboxylate (72.5 mg, 0.13 mmol) in dichloromethane (2 mL) was mixed with trifluoroacetic acid (19.7 μL, 0.26 mmol) at room temperature and stirred at room temperature for 12 hours. After completion of the reaction, ethyl acetate was added, and the organic layer was washed with saturated aqueous sodium hydrogen carbonate, dried over anhydrous sodium sulfate and evaporated under reduced pressure. The resulting residue was purified by silica gel column chromatography (ethyl acetate/methanol=20/1) to give the desired product.
