A solution of tBuOK in THF (1.0 M, 0.92 mL, 0.92 mmol) was added to a solution of (R)-4-((R)-1-hydroxyethyl)-1-((R)-1-(4-methoxyphenyl)ethyl)pyrrolidin-2-one 1.04 (128 mg, 0.486 mmol) in THF (3 mL) at room temperature. After eighteen minutes, a suspension of 4,6-dichloro-2,3-dimethyl-3H-imidazo[4,5-c]pyridine 2.47 (0.1 g, 0.463 mmol) in THF (3 mL) was added and mixture stirred at 60° C. for fifteen minutes. LC/MS indicated full conversion to desired product. Reaction mixture was quenched with water, and extracted with ethyl acetate. Organic phase was dried over MgSO4 and evaporated under reduced pressure to obtain (R)-4-((R)-1-(6-chloro-2,3-dimethyl-3H-imidazo[4,5-c]pyridin-4-yloxy)ethyl)-1-((R)-1-(4-methoxyphenyl)ethyl)pyrrolidin-2-one 2.48 that was used without further purification.
