7-Amino-3-bromo-9H-carbazole-1-carboxamide 470B (350 mg, 1.151 mmol), m-tolylboronic acid (313 mg, 2.302 mmol), PdCl2(dppf)-CH2Cl2 adduct (94 mg, 0.115 mmol), and Na2CO3 (2M) (2.88 mL, 5.75 mmol) were mixed with DME (15 mL) in a sealed microwave vial. The mixture was flushed with N2 and heated at 100° C. in an oil bath for 4 hrs. The mixture was purified using preparative HPLC to give titled product.
