Reaction Steps

To a stirring solution of 4-[(4-ethoxycarbonyl-phenyl-)hydroxy-methyl]-piperidine-1-carboxylic acid tert-butyl ester (2.145 g, 6.18 mmol) in methanol (30 mL) is added 10 mL of 1N aqueous NaOH and the reaction is heated in a 50° C. bath for 1 hour. The reaction is cooled to 0° C. and carefully acidified with 1N aqueous HCl. The reaction is extracted with dichloromethane (DCM), dried over MgSO4, filtered and concentrated to give 1.34 grams of 4-(carboxy-benzyl)-piperidine-1-carboxylic acid tert-butyl ester.
