YieldReaction ConditionsOperation in experiment
20% In ethyl acetate; Example 5 Synthesis of SA-59, SA-60 and SA-61 3-bromo-2,5-bis(3',4'-dimethoxyphenyl)thiophene (18) was prepared by the reaction of <strong>[3141-24-0]2,3,5-tribromothiophene</strong> (17) (321 mg, 1 mmol) and (3,4-dimethoxyphenyl)boronic acid (15) (419 mg, 2.3 mmol) according to the similar procedure for compound 16. The reaction mixture was purified by column chromatography (10%-30% EtOAc in hexanes) and afforded 18 (337 mg, 77% yield) as a yellow solid. SA-60 was also isolated (97 mg, 20% yield) from the reaction above as a dark yellow solid.

YieldReaction ConditionsOperation in experiment
65% In ethyl acetate; Example 6 Synthesis of SA-62 Compound 19 was prepared by the reaction of 2,5-dibromothiophene (17) (1.14 g, 5.24 mmol) and (3,4-dimethoxyphenyl)boronic acid (15) (910 mg, 5 mmol) according to the similar procedure for compound 16. The reaction mixture was purified by flash column chromatography (FCC) (5%-20% EtOAc in hexanes) and afforded compound 19 (509 mg, 34% yield) as a yellowish crystal. Compound 16 was also isolated (578 mg, 65% yield) as a yellow solid.
