실험 절차

A solution of (R)-4-((R)-1-(6-bromo-3-methyl-3H-imidazo[4,5-c]pyridin-4-yloxy)ethyl)-1-((R)-1-(4-methoxyphenyl)ethyl)pyrrolidin-2-one 2.61 (256 mg, 0.54 mmol) in TFA (8 mL) was heated at 55° C. for 16 h, cooled to rt and then evaporated to give (R)-4-((R)-1-hydroxyethyl)-1-((R)-1-(4-methoxyphenyl)ethyl)pyrrolidin-2-one 2.62 as TFA salt, which was used without purification.
