Procedure

A suspension of 11.5 g (64.18 mmol) of 2-(azetidin-1-yl)-5-nitropyridine, prepared in the preceding stage, and 1 g of Pd/C at 10% in 400 mL of ethanol is stirred vigorously at 20° C. under 5 atm of hydrogen for 4 hours. After this time, the mixture is filtered on a Celite pad and then concentrated at reduced pressure. We thus obtain 9.3 g of the expected product, which is used as it is in the rest of the synthesis.
