preparation example 1
[0100] This preparation example provides compound 134 The specific preparation method is as follows:
[0101] (1)
[0102] Under nitrogen atmosphere, in 200mL of anhydrous toluene (Tol), add raw materials in sequence: Compound A (5mmol), diphenylamine (11mmol), sodium tert-butoxide (t-BuONa) (12.5mmol), tris(dibenzylideneacetone ) Dipalladium (Pd 2 (dba)3) (0.25mmol), and 2-dicyclohexylphosphine-2',6'-dimethoxybiphenyl (S-Phos) (0.75mmol), deoxygenated for 10min, heated to 110°C, reacted 24h. After the reaction is completed, cool and filter with suction, collect the filtrate, add water and dichloromethane for extraction and separation, collect the organic phase and dry it with anhydrous sodium sulfate, collect the filtrate with suction, spin off the solvent, and purify by column chromatography to obtain the intermediate B (78% yield).
[0103] LC-MS: m / z: Calculated: C34H22N2O2S2: 554.68, Found: 554.31.
