Reaction Steps

To a mixture of 7-amino-3-bromo-9H-carbazole-1-carboxamide 470B (1 g, 2.79 mmol) and CH2I2 (15 mL) was slowly added isopentyl nitrite (1 mL, 7.48 mmol). The mixture was heated in microwave at 60° C. for 45 mins copper(I) iodide (0.266 g, 1.397 mmol) was added to the reaction mixture and heated in microwave at 55° C. for additional 30 mins The mixture was concentrated. EtOAc(50 ml) was added and stirred for 10 mins and filtered. The collected solid was washed with H2O 2×50 ml. The remaining solid was purified using preparative HPLC to give titled product.
