On a sufficient amount of anhydrous THF cooled to 0° C. 2 equivalents of a solution of AlH3-DMEA 0.5M in toluene were added. Then a solution, previously cooled to 0° C., of 1 equivalent of the previous amide in anhydrous THF was added. It was kept with stirring in an argon atmosphere at 0° C. for 30 minutes. The course of the reaction was followed by silica gel thin-layer chromatography (CH2Cl2/NH3 gas:MeOH 95:5). Water and H2SO4 10% were added to the reaction mixture and the temperature was allowed to rise slowly to 20° C. It was alkalinised with NH3 20% and extracted with AcOEt. The organic extracts, after being dried with anhydrous Na2SO4 and filtered, were evaporated to dryness. The residue obtained was purified by silica gel column chromatography (CH2Cl2/NH3 gas:MeOH, increasing polarity mixtures), providing N-(naphthalene-1-yl)-3-(2-dimethylaminoethyl)-2-methyl-1H-indene-5-sulfonamide.
