Procedure

A mixture of 400 mg of 2-methylpropan-2-yl 7-[4-nitro-3-(propan-2-yloxy)phenyl]-1,7-diazaspiro[4.4]nonane-1-carboxylate, 592 mg of hydrazine hydrate and 52.5 mg of 10% palladium-on-carbon in 10 ml of ethanol is refluxed for 1 h. The mixture is filtered and the filtrate is concentrated under reduced pressure, so as to obtain 365 mg of 2-methylpropan-2-yl 7-[4-amino-3-(propan-2-yloxy)phenyl]-1,7-diazaspiro[4.4]nonane-1-carboxylate in the form of a mauve gum.
