Conditions

Temperature
110 °C

Procedure

0.100 g (0.4 mmol) of 3-[3-(6-methoxypyridin-3-yl)piperidin-3-yl]propan-1-ol obtained in stage 1.3, in solution in 5 ml of aqueous hydrobromic acid (48% by weight solution), is introduced into a sealed tube. The reaction medium is stirred at 110° C. for 12 hours. This solution is then brought back to ambient temperature and concentrated under reduced pressure. The resulting residue is dissolved in methanol and evaporated twice under reduced pressure, and triturated from diethyl ether, to result, after filtration, in 0.150 g of the desired compound in the form of a brown powder.
