실험 절차
To a solution of 500 mg of 4,5-dihydro-5-thioxo-8-[3-(trifluoromethyl)phenyl]-3H,6H-1,4,5a,8a-tetraazaacenaphthylen-3-one (prepared as described in Example 8) in 10.0 ml of N,N-dimethylformamide was added 1.5 ml of 1N sodium hydroxide. The reaction mixture was cooled to 0° C. in an ice bath, then 0.5 ml of 30% hydrogen peroxide was added to the mixture dropwise. The reaction mixture was stirred at 0° C. for 30 minutes, then 1.0 ml of isobutylamine was added in one portion and the mixture was allowed to warm to room temperature, then was stirred for 2 hours. The solid was collected by filtration and washed with water, then ether to give 223 mg of the product of the example as a white solid, m.p. 266°-268° C. Following the procedure of Example 14 and reacting, 4,5-dihydro-5-thioxo-8-[3-(trifluoromethyl)phenyl]3H ,6H-1,4,5a,8a-tetraazaacenaphthylen-3-one with the appropriate primary aliphatic amine or cyclic secondary amine, the products of Examples 15-27 were obtained as set forth in Table III.
