실험 절차

To a solution of 1-butyn-3-yl-2-methyl-pyrrolidine in CH3CN (prepared in Example 65A assuming 100% conversion, 89 mmol) was added 4-bromo-2-iodo-phenylamine (12.0 g, 40 mmol) under nitrogen followed by addition of CuI (0.38 g, 2.0 mmol), PdCl2(PPh3)2 (0.70 mg, 1.0 mmol) and diisopropylamine (33.6 mL, 240 mmol). The resulting solution was stirred at room temperature for 2 hours, at which time analytical HPLC analysis indicated that all 4-bromo-2-iodo-phenylamine was consumed. The solvent CH3CN was removed under vacuo and the residue was extracted with IPAC (500 mL) and 5% NaHCO3 (2×300 mL). The organic layer was washed with brine, dried over Na2SO4 and concentrated under reduced pressure to give the title compound as a thick oil (11.96 g), which was used in the next step without further purification.
