(R)-4-((R)-1-(5-bromo-1-methyl-1H-benzo[d]imidazol-7-yloxy)ethyl)-1-((R)-1-phenylethyl)pyrrolidin-2-one 2.57 in TFA (2 mL) was heated in the microwave for 30 min at 140° C. The reaction mixture was then concentrated to give (R)-4-((R)-1-(5-bromo-1-methyl-1H-benzo[d]imidazol-7-yloxy)ethyl)pyrrolidin-2-one 2.58, which was used without further purification.
