YieldReaction ConditionsOperation in experiment
70.9% With potassium carbonate; In N,N-dimethyl-formamide; for 72.0h; 187.6 g (0.630 mol) of the compound represented by the formula 3-b obtained from the above reaction formula 16 and 5.8 L of N, N-dimethylformamide were added to a 10 L round bottom flask, and 226.3 g (1.637 mol) of potassium carbonate was added 155.1 g (1.291 mol) of ethyl 2-mercaptoacetate was added thereto, followed by stirring for 3 days. The reaction mixture was poured into water and extracted with methylene chloride. The organic layer was separated, concentrated under reduced pressure, and dried to obtain 152.0 g (70.9%) of the compound represented by the formula (3-c).

YieldReaction ConditionsOperation in experiment
65% With tetrakis(triphenylphosphine) palladium(0); potassium carbonate; In tetrahydrofuran; water; at 85℃; for 12h;Inert atmosphere; General procedure: Pd(PPh3)4 (20 mol%), 2 M K2CO3 aqueous solutions (6 ml) were added to a solution of boronic ester derivative (0.25 mmol) and 3,4-dibromothiophene-2,5-dicarbaldehyde (0.2 mmol) in THF (12 mL)under argon condition. After heating the mixture to 85 C for 12 h, it was cooled to room temperature (RT), THF solution evaporated under reduced pressure and extracted with chloroform and brine solution. Finally, chloroform part was dried over anh. MgSO4. The desired product was purified by silica gel column using EtOAc hexane1:2 as eluent mixture.
