실험 절차

To the crude material from Step 1 was added DMF (1.5 ml) followed by cesium carbonate (175 mg, 0.538 mmol) and bromoacetonitrile (24.99 μl, 0.359 mmol). The resulting mixture was stirred at 60° C. overnight affording clean conversion to desired product according to LC-MS. The mixture was filtered through Celite with the aid of DCM and the filtrate dried under reduced pressure. m/z (ESI) 577.1 (M+H)+.
