실험 절차

In a similar manner to Step 2 of Example 1, 3-amino-6-bromophthalimide (80.0 mg, 0.332 mmol) was dissolved in acetonitrile (4.0 mL), and, the solution was treated with 2-benzofuraneboronic acid (161 mg, 0.996 mmol), palladium acetate (9.0 mg, 0.040 mmol), tri(o-tolyl)phosphine (24.3 mg, 0.080 mmol) and triethylamine (0.463 mL, 3.32 mmol), followed by purification by preparative thin-layer chromatography (chloroform/acetonitrile=15/1) to obtain Compound 171 (30.1 mg, yield 33%).
