Procedure
In 45 ml of dimethylformamide was dissolved 6.0 g (31.8 mmol) of ethyl 5-chloromethyl-2-furancarboxylate followed by addition of 9.64 g (95.5 mmol) of 4-hydroxypiperidine and the mixture was stirred at room temperature for 20 hours. The solvent was then distilled off under reduced pressure and the residue was diluted with 100 ml of chloroform and washed with saturated aqueous sodium chloride solution twice. The organic layer was dried over anhydrous magnesium sulfate and the solvent was distilled off to give 7.84 g (97.4%) of ethyl 5-(4-hydroxypiperidinomethyl)-2-furancarboxylate (Compound s) as light brown oil.
