Reaction Steps

In a microwave tube, 470 mg of 2-methylpropan-2-yl 6-ethyl-4-[4-nitro-3-(propan-2-yloxy)phenyl]-3,6-dihydropyridine-1(2H)-carboxylate are introduced into 20 ml of methanol. 456 mg of ammonium formate and 385 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. The residue is taken up with 30 ml of ethyl acetate and 3 ml of water. The organic phase is dried over magnesium sulfate, filtered and concentrated under reduced pressure, so as to obtain 370 mg of 2-methylpropan-2-yl 4-[4-amino-3-(propan-2-yloxy)phenyl]-2-ethylpiperidine-1-carboxylate in the form of a colourless oil.
