실험 절차

1-(2-{[tert-butyl(dimethyl)silyl]oxy}-1,1-dimethylethyl)-3-iodo-1H-pyrrolo[3,2-c]pyridine (Preparation 65, 1.81 g, 4.20 mmol) was dissolved in THF (25 mL) and the solution was degassed and cooled to −5° C. 2M iPrMgCl in THF (2.52 mL, 5.05 mmol) was added dropwise and the reaction stirred at this temperature for 45 minutes. A solution of 5-bromo-N-methoxy-N-methylnicotinamide (1.24 g, 5.05 mmol) in THF (3 mL) was added dropwise and the reaction warmed to room temperature for 4.5 hours. The reaction was partitioned between saturated aqueous ammonium chloride solution (20 mL) and EtOAc (30 mL). The organic layer was collected, dried and concentrated in vacuo. The residue was purified using silica gel column chromatography eluting with 100% DCM to 50:50 DCM:EtOAc to afford the title compound as a colourless oil (1.05 g, 62%).
