Fangchinoline (1 g, 1.64 mmol) was addedto dimethylsulfoxide (5 mL), followed by the addition ofpotassium tert-butoxide (560 mg, 4.91 mmol) at 0 C. After the mixed solution was stirred for 0.5 brat room temperature, cyeloehloroethane (180 mg, 1.97 mmol) dissolyed in dimethylsulfoxide (2 mL) was added dropwise thereto. The reaction solution was heated up to 40 C. and stirred for 3 br. After the reaction was complete, water (50 mL) was added to the reaction solution at 0 C. and diehloromethane (10 mL*4) was used for extraetion. The organie phases were combined, washed with saturated salt solution, dried and rotayapped. The resulted produet BS-EC-400 was direetly used in the subsequent reaction without purilkation.
