실험 절차

To a solution of 1-(5-amino-1H-indazol-1-yl)-2,2-dimethylpropan-1-one maleate salt (580 mg, 1.7 mmol, prepared as described in U.S. Ser. No. 08/021,4614) and 2-benzyl-2-azabicyclo[2.2.1]heptan-7-one (250 mg, 1.7 mmol) (J. R. Malpass, S. Handa, and R. White, Org. Lett., 2005, 7, 2759-2762) in THF (9 mL) was added sodium triacetoxyborohydride (740 mg, 3.5 mmol), and the mixture was stirred at ambient temperature for 24 h. The reaction mixture was partitioned between aqueous sodium bicarbonate and ethyl acetate, and the organic layer was washed with brine and dried over sodium sulfate. The solvent was evaporated and the residue was purified by normal phase chromatography followed by reversed phase HPLC to afford 175 mg (25%) of 1-(5-((1SR,4SR,7RS)-2-benzyl-2-azabicyclo[2.2.1]heptan-7-ylamino)-1H-indazol-1-yl)-2,2-dimethylpropan-1-one.
