Reaction Steps
A mixture of 4-(6-fluoro-1-methyl-1H-indazol-3-yl)piperidine (5.0 g; 0.02 mol), potassium carbonate (8.28 g; 0.06 mol), 3-bromopropanol (2.98 g; 0.02 mol) and acetone (100 ml) was stirred and refluxed for 20 h. The reaction mixture was filtered, concentrated in vacuo and purified by chromatography on silica gel 60 with ethyl acetate:methanol (8:2, v/v) as eluent. Concentration of the appropriate fractions afforded 2.1 g (34%) of 4-(6-fluoro-1-methyl-1H-indazol-3-yl)-1-(3-hydroxypropyl)piperidine.
