2,2,2-Triphenylacetohydrazide (48.2 mg, 0.159 mmol) was dissolved in anhydrous toluene (3 mL) and stirred at room temperature under nitrogen. 8-Methoxy-2,3,4,5,6,7-hexahydroazocine (24.7 mg, 0.175 mmole) was added and the solution was stirred at 120° C. overnight and 200° C. for two days. After cooling, the toluene was removed by evaporation and crude product was purified by silica gel chromatography (100% ethyl acetate→5% methanol in ethyl acetate→10% methanol in ethyl acetate) to give the product (2-1) as a white solid (12.4 mg).
