Procedure
To a suspension of 3-iodo-1H-pyrrolo[3,2-c]pyridine (Preparation 47, 82 g, 340 mmol) and cesium carbonate (164 g, 504 mmol) in DMF (650 mL) was added 2-iodopropane (30.7 mL, 307 mmol) dropwise over 25 minutes at room temperature and the reaction was stirred for 6 hours. The reaction was poured into water (500 mL), stirred for 10 minutes and extracted into EtOAc (4×350 mL). The organic layers were combined, washed with brine, passed through a phase separation cartridge and concentrated in vacuo. The residue was purified using silica gel column chromatography eluting with DCM followed by 50% EtOAc in DCM to afford the title compound as a pale brown gum (93 g, 61%).
