实验步骤: To a solution of 1-(4-ethylpiperazin-1-yl)-3-(4-hydroxyphenyl)isoquinoline (0.30 g) obtained in Example 7 in tetrahydrofuran (15 ml) was added 60% sodium hydride (36 mg) at room temperature. After the evolution of hydrogen was ceased, bromopropionitrile (0.14 g) was added thereto, and the resulting mixture was reacted at room temperature for 12 hr. Ethyl acetate and an aqueous solution of ammonium chloride were added to the reaction solution, and the resulting organic layer was then separated, washed with water, dried and concentrated. To the resulting residue were added ethanol and a 2N aqueous solution of hydrochloric acid, and the resulting mixture was reacted at 50° C. for 30 min, followed by the evaporation. The resulting residue was partitioned between ethyl acetate and water. The resulting organic layer was washed with water and brine, and dried. The solvent was removed, and the resulting residue was purified by NH-silica gel column chromatography (ethyl acetate/hexane system), to give the title compound as a pale yellow oil. The oil was converted into a hydrochloride in a conventional manner, to give 0.12 g of the title compound as a yellow powder. the resulting mixture was reacted at room temperature for 12 hr the resulting organic layer was then separated washed with water dried concentrated To the resulting residue were added ethanol a 2N aqueous solution of hydrochloric acid, and the resulting mixture was reacted at 50° C. for 30 min followed by the evaporation The resulting residue was partitioned between ethyl acetate and water The resulting organic layer was washed with water and brine dried The solvent was removed the resulting residue was purified by NH-silica gel column chromatography (ethyl acetate/hexane system)

实验步骤: Add potassium hydroxide (10.8 g, 192 mmol) to a solution of 3-tert-butoxycarbonyl-7-chloro-6-dimethylcarbamoylthio-2,3,4,5-tetrahydro-1H-benzo[d]azepine (3 g, 7.8 mmol) in degassed methanol (150 mL) under a nitrogen atmosphere. Heat the mixture at 80° C. for 6 h. Cool the mixture to ambient temperature, then concentrate in vacuo to an oil. Dissolve the oil in EtOAc (50 mL), wash with aqueous saturated ammonium chloride (30 mL). Separate the organic layer and extract the aqueous layer with EtOAc (3×50 mL).
