反応手順
To a stirred solution of 2-(4-chlorophenyl)-N-[5-(7H-pyrrolo[2,3-d]pyrimidin-5-ylcarbonyl)pyridin-3-yl]acetamide (Example 308, 50 mg, 0.13 mmol) in DMF (1 ml) was added Cs2CO3 (75 mg, 0.23 mmol) followed by 2-bromoacetamide (21.3 mg, 0.154 mmol). The reaction was then stirred at room temperature overnight. The reaction was quenched with water (5 mL) and extracted with EtOAc (3×5 mL). The organics were combined, washed with water (5 mL) then brine (5 mL), dried over anhydrous magnesium sulfate and concentrated in vacuo. Purification by preparative HPLC gave the title compound in 59% yield, 34 mg.
