Reaction Steps

A solution 1.5M n-BuLi in hexanes (160 μL, 0.24 mmol) was added to a solution of the 5-bromo-3-(2-methoxy-phenyl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine (91.5 mg, 0.20 mmol) in 2 ml THF at −78° C. The mixture was stirred at −78° C. for 30 minutes before 3,4,5-trimethoxy-benzaldehyde (94.2 mg, 0.48 mmol) in 3 mL of THF was added. The mixture was stirred at −78° C. for 1 hour and then at 0° C. for 30 minutes, quenched with MeOH, and then concentrated. The crude residue was purified by silica gel chromatography using a gradient of ethyl acetate in hexanes to give [3-(2-Methoxy-phenyl)-1H-pyrrolo[2,3-b]pyridin-5-yl]-(3,4,5-trimethoxy-phenyl)-methanol (32 mg, 38% yield) as a white solid. MS: m/z 420.1 [MH+].
