実験手順

A mixture of 4-isothiocyanato-2-trifluoromethylbenzonitrile (1a) (0.51 g, 2.22 mmol) and 4-(1-cyanocyclobutylamino)benzoic acid (51a) (0.343 g, 1.59 mmol) in DMF (2 ml) was heated under microwave irradiation at 60° C. and stirred for 16 hours. To this mixture were added methanol (10 ml) and aq. 2M HCl (5 ml). The second mixture was refluxed for 12 hours. After being cooled to room temperature, the reaction mixture was poured into cold water (20 ml) and extracted with ethyl acetate (3×30 ml). The organic layer was dried over MgSO4, concentrated and chromatographed (dichloromethane:acetone, 95:5) to yield 4-[7-(4-cyano-3-trifluoromethylphenyl)-8-oxo-6-thioxo-5,7-diazaspiro[3.4]oct-5-yl]-benzoic acid methyl ester (51b) [RD159] (0.09 g, 0.196 mmol, 12%), the structure of which is illustrated in Formula 25, as a white powder and N-(3-cyano-4-trifluoromethylphenyl)-4-[7-(4-cyano-3-trifluoromethylphenyl)-8-oxo -6-thioxo-5,7-diazaspiro[3.4]oct-5-yl]benzamide (51b′) [RD160] (0.28 g, 0.45 mmol, 29%), the structure of which is illustrated in Formula 26, as a white powder.
