실험 절차
Ethyl 5-(2-chloroacetylamino)-4-(2-chlorobenzoyl)thiophene-2-carboxylate (325 g) and sodium iodide (151.3 g) were added to tetrahydrofuran (3500 ml), and the mixture was refluxed under heating for 1.5 hours. The mixture was cooled to -65° C., and ammonia (164 ml) was added. The reaction temperature was raised slowly to room temperature. The solvent was evaporated, and chloroform and water were added. The organic layer was taken out, washed with water and dried over sodium sulfate. The solvent was evaporated. Toluene (7 l) and silica gel (1365 g) were added thereto, and the mixture was refluxed under heating for 1.5 hours. The silica gel was collected by filtration, and a mixed solvent of chloroform-methanol (10:1) was added to elute the obtained product. The solvent was evaporated, and ethyl acetate was added. The resulting crystals were collected by filtration and washed with ethyl acetate to give 70.0 g of ethyl (5-(2-chlorophenyl)-1,2-dihydro-3H-thieno[2,3-e] [1,4]diazepin-2-on-7-yl)-carboxylate.
