Procedure

A mixture of 160 mg of 1-methyl-7-[4-nitro-3-(propan-2-yloxy)phenyl]-1,7-diazaspiro[4.4]nonane, 301 mg of hydrazine hydrate and 27 mg of 10% palladium-on-carbon in 30 ml of ethanol is heated at 80° C. (bath) for 2 h. The mixture is filtered and the filtrate is concentrated under vacuum, so as to obtain 141 mg of 4-(1-methyl-1,7-diazaspiro[4.4]non-7-yl)-2-(propan-2-yloxy)aniline in the form of a brown oil.
