Embodiment 1
[0096]
[0097] Add compound A (11.68g, 20mmol), THF 100ml and magnesium strips 1.2g sequentially into a 250ml three-neck flask, replace with nitrogen, heat and stir for 30min. Dissolve the compound dimethyltin chloride (4.38g, 20mmol) in 60ml of toluene, slowly add the solution dropwise to the reaction system, after the dropwise addition, naturally rise to room temperature and react for 6h, after the reaction is completed, add 60ml of ice water to quench the reaction , the reaction solution was extracted with DCM (100ml*3) and saturated brine (100ml*2) respectively, the organic phase was rotary evaporated to obtain an oil, and the solid B was obtained by recrystallization using TOL / EtOH.
[0098] The structural confirmation data is as follows: MALDI-TOF: 573.01;
[0099] 1 H NMR (400MHz, Chloroform) δ7.55(s,2H),7.37(s,2H),7.33(s,2H),7.23(d,J=10.0Hz,4H),7.15(s,2H),7.08 (s,2H),7.00(s,2H),6.51(s,2H),1.64(s,6H).
