Ethyl 2-[4-(ethoxycarbonyl)piperidin-1-yl]-6-azaspiro[3.4]octane-6-carboxylate (2.474 g, 7.32 mmol) was dissolved in THF (25 mL) at rt and 1 M LiOH sol. (7.32 mL) was added. The reaction mixture was stirred at rt over the weekend. The reaction mixture was adjusted to pH 5 by addition of 1 M HCl sol. and solvents were removed in vacuo, to give 1-[6-(ethoxycarbonyl)-6-azaspiro[3.4]oct-2-yl]piperidine-4-carboxylic acid which was used directly without further purification.
