実験手順

A solution of 10 g of 1-methyl-4-[4-nitro-3-(propan-2-yloxy)phenyl]pyridinium iodide in 280 ml of methanol is hydrogenated in an autoclave on 2.9 g of platinum oxide hydrate, at a hydrogen pressure of 15 bar and at ambient temperature for 4 h. The catalyst is removed by filtration on Clarcel and the mixture is concentrated under vacuum. The residue is taken up in 200 ml of ethyl acetate and washed with 200 ml of 1M sodium hydroxide and then with a saturated sodium chloride solution. The organic phase is dried over magnesium sulfate and concentrated under vacuum, so as to obtain 6.0 g of 4-(1-methylpiperidin-4-yl)-2-(propan-2-yloxy)aniline.
