To a stirred suspension of NaH (98 mg, 2.5 mmol, 60% in mineral oil) in THF (10 mL), 4-methoxy-2-methyl-1H-pyrrolo[3,2-c]pyridine 3 (280 mg, 1.72 mmol) in THF (3 mL) was added. The mixture was stirred at room temperature for 30 min, and then 1-iodooctane (0.41 mL, 2.2 mmol) was added, stirring was continued for 18 h. The reaction mixture was quenched with saturated NH4Cl (20 mL), extracted with EtOAc (3×40 mL). The combined organic extracts were washed with water (40 mL), brine (40 mL), dried over Na2SO4 and evaporated. Flash chromatography of the residue over silica gel, using 10% EtOAc in hexanes to 20% EtOAc in hexanes) gave product 8 as a yellow oil. Yield: 231 mg (49%).
