Reaction Steps

In a microwave tube, 400 mg of 1′-methyl-5-nitro-4-(propan-2-yloxy)-1′,2′,3′,6′-tetrahydro-2,4′-bipyridine are introduced into 30 ml of methanol. 546 mg of ammonium formate and 333 mg of Pd/C (10%) are added. The reaction medium is microwave-heated at 80° C. for 5 minutes. The mixture is filtered on Clarcel and the Clarcel is rinsed with methanol. The filtrate is concentrated under reduced pressure, so as to give 380 mg of 6-(1-methylpiperidin-4-yl)-4-(propan-2-yloxy)pyridin-3-amine in the form of a brown oil.
