example 1
[0043] Preparation of:
[0044] At -78°C, add 1 part of 3-bromofuran into anhydrous THF, add 1 part of BuLi dropwise, stir for 0.5-3 hours, and then move to room temperature. Add 1 to 2.0 parts of dimethyl disulfide to the above mixture, stir for 10 to 24 hours, quench with saturated ammonium chloride, extract with dichloromethane, dry and spin dry, and pass through a column to obtain 3-thiomethylfuran.
[0045] At 0°C, add 1 part of 3-thiomethylfuran into dichloromethane, add 1 part of bromine, stir for 2.5-5.0 hours, add saturated NaHSO 3 Or sodium thiosulfate solution, extract the organic phase and dry it, and pass through the column to obtain 2-bromo-3-thiomethylfuran
[0046] Take 2.2-3.0 parts of 2-bromo-3-thiomethylfuran and add it to THF, 2 Or add 2 to 10% Pd(PPh under the protection of Ar 3 ) 4 , Heated to reflux for 24 ~ 48h. The THF was spun out, the organic phase was extracted and dried, and passed through the column to obtain 2,5-(2-(3-thiomethyl)furan)fura...
