Procedure
To a solution of 2-(3-iodo-1H-pyrrolo[3,2-c]pyridin-1-yl)propan-1-ol (Preparation 56, 11.5 g, 38.1 mmol) and imidazole (6.48 g, 95.2 mmol) in DCM (300 mL) was added a solution of TBDMSCl (6.95 g, 45.7 mmol) in DCM (50 mL) dropwise at 0° C. The reaction was allowed to warm to room temperature and stirred for 1.5 hours. To the reaction was added water (500 mL) and DCM (200 mL), the organic layer collected, dried over MgSO4 and concentrated in vacuo. The residue was purified using silica gel column chromatography eluting with 0-10% MeOH in DCM to afford the title compound (15 g, 100%).
