실험 절차

A mixture of 2-bromo-5-nitrothiophene (478 mg, 2.3 mmol), 3-cyclobutyl-2,3,4,5-tetrahydro-1H-benzo[d]azepin-7-ol (E3) (500 mg, 2.3 mmol) and potassium carbonate (765 mg, 5.5 mmol) in dimethylformamide (10 ml) was stirred at 80° C. for 16 hours. The reaction mixture was cooled, diluted with ethyl acetate and washed with water, brine and dried (sodium sulfate). Concentration in vacuo and purification of the resulting residue by column chromatography 0.880 ammonia:methanol:dichloromethane (1:8:300) afforded the title compound (E211); MS (ES+) m/e 345 [M+H]+.
