実験手順

Methyl 4-{5-[(1R,2S)-2-amino-1-phenylpropoxy]-1H-indazole-1-yl}benzoate (64.3 mg, 0.16 mmol) is dissolved in 6.1 mL of dichloromethane. Triethylamine (0.053 mL, 0.38 mmol) and 2-furoylchloride (20.9 mg, 0.16 mmol) are added. After 4 h stirring at r.t. the reaction mixture is diluted with dichloromethane, washed with water and brine and dried over Na2SO4. The reaction mixture is filtered, the solvent evaporated and the residue purified by chromatography (silicagel, eluents: ethyl acetate/hexane). 38.2 mg (48.1%) of the title compound are obtained.
