实验步骤: Starting from 1.02 g (0.005 mol) of 5-acetylamino-2-tetralone and 1.7 g (0.01 mol) of trans-cinnamylamine-hydrochloride the title compound is obtained analogously to Example 4.1.11 in a yield of 1.1 g (61.6% of theory) and with a melting point of 257° C., which does not change after recrystallisation from methanol/ether.

实验步骤: To 10 ml of a solution of 438 mg (2.0 mmol) of 2,4-dichloro-7-metylthieno[3,2-d]pyrimidine and 445 mg (4.4 mmol) of triethylamine in DMF was added 339 mg (2.0 mmol) of trans-cinnamylamine hydrochloride under ice cooling. The reaction mixture was stirred at the same temperature for one hour and then allowed to resume room temperature, followed by stirring for further 2 hours. After completion of the reaction, ice water was added to the reaction mixture, followed by extraction with ethyl acetate (50 ml×3). After the organic layer was washed successively with 1N hydrochloric acid, water and brine and dried over anhydrous sodium sulfate, the solvent was distilled off under reduced pressure. The residue was purified by silica gel chromatography (eluent: ethyl acetate-hexane=1/4) to give 341 mg (yield: 54.0%) of the title compound. to resume room temperature by stirring for further 2 hours was added to the reaction mixture followed by extraction with ethyl acetate (50 ml×3) After the organic layer was washed successively with 1N hydrochloric acid, water and brine dried over anhydrous sodium sulfate the solvent was distilled off under reduced pressure The residue was purified by silica gel chromatography (eluent: ethyl acetate-hexane=1/4)
