[0028] Mix 60gNaOH with 480mLH 2 The solution prepared by O was poured into a reaction flask, thiophenol (75mL, 0.63mol) was taken, and then chloroacetic acid (78g, 0.825mol) was added, and a large amount of white precipitates were precipitated in the reaction solution. 6N HCl was added to obtain phenylthioacetic acid (5) as a white solid. Dissolve 5 (20g, 0.12mol) in 90mL glacial acetic acid, add 24.3mL30% H 2 o 2 , stirring at room temperature. After the reaction is complete, add HNO 3 48mL. Heating reaction, after 4 hours, white needle-like crystals precipitated, filtered and dried to obtain 3,4-diphenylsulfonylfurazan nitrogenoxide (7). 7 (219.6 mg, 0.6 mmol) was dissolved in 5 mL CH 2 Cl 2 In, take evodiamine (1) (104mg, 0.3mmol), add DBU (0.4mmol) to CH 2 Cl 2 In, stir for 3h. The reaction was monitored by T...
