実験手順: To a slurry of 46.5 gm (0.348 mole) AlCl3 in 400 mL dichloromethane at -78° C. was added a solution of 32.76 gm (0.174 mole) of the previously prepared o-chlorophenylacetyl chloride in 100 mL dichloromethane dropwise over 1 hour. The dry ice/acetone bath then was replaced with an ice/water bath and ethylene was bubbled into the reaction mixture during which time the temperature rose to 15° C. The ethylene addition was discontinued at the end of the exotherm and the reaction mixture was stirred at about 5° C. for 4 hours. Ice was then added to the reaction mixture to destroy aluminum complexes. Upon termination of the exotherm, the reaction mixture was diluted with 500 mL of water and stirred vigorously until all solids had dissolved. The phases were separated and the organic phase was washed with 3×400 mL 1N hydrochloric acid and 2×400 mL saturated aqueous sodium bicarbonate. The remaining organic phase was then dried over sodium sulfate and concentrated in vacuo to give a pale orange residue. The residue was dissolved in 1:1 hexane:diethyl ether and was poured over a flash silica column which was then eluted with 1:1 hexane:diethyl ether to give a light yellow residue which was crystallized from 4:1 hexane:diethyl ether to give 10.55 gm of the title compound. ethylene was bubbled into the reaction mixture during which time the temperature rose to 15° C The ethylene addition Ice was then added to the reaction mixture to destroy aluminum complexes Upon termination of the exotherm, the reaction mixture was diluted with 500 mL of water stirred vigorously until all solids had dissolved The phases were separated the organic phase was washed with 3×400 mL 1N hydrochloric acid and 2×400 mL saturated aqueous sodium bicarbonate The remaining organic phase was then dried over sodium sulfate concentrated in vacuo to give a pale orange residue was then eluted with 1:1 hexane diethyl ether to give a light yellow residue which was crystallized from 4:1 hexane

実験手順: A mixture of 30.0 gm (0.176 mole) of o-chlorophenyl-acetic acid and 40.0 mL of thionyl chloride was stirred at ambient temperature for 18 hours. The volatiles were then removed in vacuo to give 32.76 gm (99.0 %) of o-chloro-phenylacetyl chloride as a transparent, pale yellow, mobile liquid. The volatiles were then removed in vacuo

実験手順: 2-Chlorophenylacetic acid (51 mg, 0.3 mmol) was dissolved in ethyl acetate (1.5 mL), the solution was added with thionyl chloride (26 μL, 0.36 mmol), and the mixture was refluxed by heating for 4 hours. The solvent was evaporated under reduced pressure to give 2-chlorophenylacetyl chloride. By using this compound and 5-(4-aminophenyl)-1H-naphtho[1,2-b][1,4]diazepine-2,4(3H,5H)-dione (190 mg, 0.6 mmol) obtained in Example 1, (3), the title compound (10 mg, yield 11%) was obtained as pale yellow crystals in the same manner as that of Example 1, (4). the mixture was refluxed by heating for 4 hours The solvent was evaporated under reduced pressure
