Yield: 93%

Reaction Conditions:

tetrakis(triphenylphosphine) palladium(0) in toluene for 12 h;Inert atmosphere;Reflux;

Steps:

3
(Synthesis Example 3) After synthesizing compound G, it was used to synthesize compound H as an intermediate compound. After placing 2-tributylstannylthiophene (4.27 g, 11.43 mmol) and 1,3,5-tribromobenzene (1.0 g, 3.18 mmol) in a 20 mL nitrogen-substituted two-necked flask, dry toluene (5 mL) was added. After deaeration by bubbling, tetrakistriphenylphosphinepalladium(0) (92 mg, 0.080 mmol) was added and the mixture was heated to reflux for 12 hours. The solid was removed by Celite filtration, concentrated under reduced pressure and purified by column chromatography (silica gel, hexane/dichloromethane = 10/1 (volume ratio)) to obtain compound G represented by formula (28) (964 mg, 93% yield).
