Procedure

0.48 g of platine (IV) oxide (2.12 mmol) is added to a solution of 26.8 g of 4-(4-(tert-butoxycarbonyl)-3-nitrophenyl)-1-methylpyridinium iodide (60.6 mmol) in 200 mL of methanol placed in a reactor made in stainless steel. The reaction medium is brought under 5 bar of hydrogen for 24 h. The catalyst is filtered and the filtrate is concentrated under reduced pressure to yield 24.8 g (98%) of white crystals.
