実験手順: A mixture of 1.42 g of 4-fluoro-1-nitro-2-(propan-2-yloxy)benzene, 1.0 g of 1-methyl-1,7-diazaspiro[4,4]nonane and 1.48 g of potassium carbonate in 10 ml of DMSO is stirred at ambient temperature overnight. The mixture is diluted with 160 ml of water and extracted three times with 100 ml of ethyl acetate. The organic phases are dried over magnesium sulfate and concentrated under vacuum. The yellow oily residue is purified on silica, with an elution gradient with dichloromethane/methanol (100/0 then 90/10), so as to obtain 160 mg of 1-methyl-7-[4-nitro-3-(propan-2-yloxy)phenyl]-1,7-diazaspiro[4.4]nonane in the form of an orangey-coloured oil. extracted three times with 100 ml of ethyl acetate The organic phases are dried over magnesium sulfate concentrated under vacuum The yellow oily residue is purified on silica, with an elution gradient with dichloromethane/methanol (100/0
