Reaction Steps

50 mg of the 2-chloro-8,8-dimethyl-5-(pyridin-3-ylamino)-6-(trifluoromethyl)-5,6,7,8-tetrahydronaphthalene-1,6-diol that is described in Example 159 is dissolved in 0.12 ml of 1-methyl-2-pyrrolidinone and mixed with 12.6 mg (0.258 mmol) of sodium cyanide and 28.2 mg (0.129 mmol) of nickel(II) bromide. The reaction mixture is brought to reaction in the microwave as described in the literature (J. Org. Chem. 68, 9122 (2003) (200° C., 20 bar). After cooling, the reaction mixture is diluted with ethyl acetate and then a small amount of water is added. The mixture is filtered over Extrelut (mobile solvent ethyl acetate). The solvent is spun off, and the residue is chromatographed on silica gel (mobile solvent methanol/dichloromethane). 9.4 mg (19.2%) of the desired nitrile is isolated.
