Pyrrolidine → 4-(5-Bromo-pyridin-2-ylmethoxy)-1-[2-(4-pyrrolidin-1-ylmethyl-phenyl)-ethyl]-1H-pyridin-2-one

Participants

Reaction Steps

To 90 mg (0.19 mmol) 1-[2-(4-bromomethyl-phenyl)-ethyl]-4-(5-bromo-pyridin-2-ylmethoxy)-1H-pyridin-2-one (example 12.1b) in 2.0 mL acetonitrile is added at RT 63 μL (0.75 mmol) pyrrolidine. The reaction mixture is stirred for 2 h at RT and is directly transferred to a reverse HPLC for purification (Waters symmetry, C18; water (0.15% formic acid)/acetonitrile 95:5 to 10:90).
