실험 절차

4-(1H-5-Indazolylamino)-1-cyclohexanone (intermediate 3) (57 mg) and 1-aminoindan (67 mg) were dissolved in methanol (1 ml), and sodium triacetoxyborohydride (105 mg) was added by portions to the solution at room temperature. The reaction mixture was stirred at room temperature for 18 hr. Hydrochloric acid-methanol was then added thereto, and the reaction mixture was stirred and was then concentrated. The residue was purified by HPLC [0.5% aqueous trifluoroacetic acid solution/acetonitrile]. A saturated aqueous sodium hydrogencarbonate solution (2 ml) was then added to fractions containing respective compounds, followed by extraction with chloroform-propanol (3/1). The organic layers were dried over anhydrous sodium sulfate, and the solvent was removed by distillation under the reduced pressure to give an anti-form compound (17 mg) and a syn-form compound (18 mg).
