실험 절차

A mixture of intermediate 38 (0.10 g, 0.32 mmol), 3-bromo-benzenesulfonamide (0.10 g, 0.42 mmol), Pd2(dba)3 (20 mg, 0.022 mmol), Xantphos (25 mg, 0.043 mmol) and cesium carbonate (0.20 g, 0.61 mmol) in dioxane/DMF (3/1, 4 mL) was sealed in a microwave reaction tube and irradiated with microwave at 170° C. for 25 min. After cooling to room temperature, the cap was removed and the resulting mixture filtered and the filtered solid washed with DCM. The filtrate was concentrated and the residue purified by HPLC. The corrected fractions were combined and poured into saturated NaHCO3 solution (30 mL). The aqueous layer was extracted with EtOAc (2×30 mL) and the combined organic layers washed with brine, dried over anhydrous Na2SO4 and filtered. The filtrate was concentrated and solid triturated in a mixture of EtOAc/hexanes (1/10, 33 mL). After filtration, the title compound was obtained as a white solid (11 mg, 7%).
