Reaction Steps

A solution of hydrochloric acid (12N, 1.5 mL) in dioxane (7.5 mL) is added to 4-benzyloxymethylpiperidine-1,4-dicarboxylic acid-1-tert butyl ester-4-ethyl ester (1.9 g, 0.005 mol) and stirred at room temperature for 30 minutes. The reaction mixture is concentrated under reduced pressure and the residue is treated with aqueous solution of sodium bicarbonate to adjust the pH to 8-9. It is again concentrated under reduced pressure and the residue is treated with dichloromethane. After drying over sodium sulfate solvent is removed to get 4-benzyloxymethylpiperidine-4-carboxylic acid ethyl ester.
