Reaction Steps

A mixture of 0.75 g of 5-fluoro-1-nitro-2-(propan-2-yloxy)benzene, 0.42 g of 4-aminotetrahydropyran and 0.8 g of potassium carbonate in 6 ml of DMSO is stirred at 50° C. overnight. The mixture is diluted with 100 ml of water and extracted three times with 50 ml of ethyl acetate. The organic phases are combined and then dried over magnesium sulfate and concentrated to dryness under reduced pressure. The residue is purified by chromatography on a 50 g silica column, elution being carried out with a dichloromethane/methanol (95/5 v/v) mixture, so as to obtain 0.69 g of (3-isopropoxy-4-nitrophenyl)(tetrahydropyran-4-yl)amine in the form of a yellow foam.
