Procedure
To a stirred mixture of ethyl 1-(3-methoxy propyl)piperidin-4-carboxylate (33.0 grams, 144.1 mmol, obtained in the above step), tetrahydrofuran (200 mL) and water (200 mL) was added lithium hydroxide monohydrate (6.1 grams, 144.1 mmol). The reaction mixture was stirred at room temperature for 16 hours before being diluted with ethylacetate. The two layers were separated and the aqueous layer was acidified to pH: 3-4 with concentrated hydrochloric acid and the volatiles were removed under reduced pressure to obtain 1-(3-methoxy propyl)piperidin-4-carboxylic acid (35.0 grams).
