Reaktionsschritte

A mixture of 4-(6-fluoro-1-methyl-1H-indazol-3-yl)piperidine (1 g; 4.3 mmol) and phenyloxirane (0.6 g; 5 mmol) in 10 ml acetonitrile was refluxed for 16 h. The cooled reaction mixture was concentrated in vacuo and purified by chromatography on silica gel 60 with ethyl acetate: methanol (9:1, v/v) as eluent. Concentration of the appropriate fractions gave 500 mg (33%) of 1-(2-hydroxy-2-phenyl-ethyl)-4-(6-fluoro-1-methyl-1H -indazol-3-yl)-piperidine.
