To a mixture of 5-chloro-1H-pyrrolo[3,2-b]pyridine (0.50 g, 3.3 mmol, Adesis) and K2CO3 (1.4 g, 9.8 mmol) in DMF (12 mL) at 0° C. was added benzyl bromide (0.43 mL, 3.6 mmol, Aldrich) dropwise. The mixture was allowed to warm to ambient temperature and stir overnight. The reaction mixture was partitioned between EtOAc and water. The organic layer was washed with water (3×), brine, dried over sodium sulfate, filtered and concentrated. Flash chromatography, eluting with a gradient from 0-20% EtOAc in hexanes afforded product as a clear oil (0.77 g, 97%).
