Yield:1269004-56-9 85%
Reaction Conditions:
with potassium phosphate in tetrahydrofuran;water; for 4 h;Inert atmosphere;Reflux;Suzuki Coupling;
Steps:
4 Synthesis Example 4
Charge a four-neck flask with the above-prepared compound (c) (1.5 g, 2.2 mmol), 2-thiophene boronic acid (630 mg, 4.9 mmol), Pd(Pt13u3)2 (150 mg, 0.22 mmol), K3P04 aqueous solution (10 ml, 20% by weight), and THF (50 nil), and reflux for 4 hours under Ar atmosphere. Cool thereaction liquid to room temperature and wash it with MeOR. Thus, a blue solid (1.3 g, 85%) is obtained. mlz=689.2 (M+H)
