Participants

Reaction Steps

Trifluoroacetic acid (1 mL) was added to a solution of 5-fluoro-1-{(3R)-3-(methylsulfonyl)-3-[(tetrahydro-2H-pyran-2-yloxy)amino]butyl}-4-[4-(oxetan-3-yloxy)phenyl]pyridin-2(1H)-one (164 mg, 0.304 mmol) in DCM (10 mL). The reaction was allowed to stir at rt overnight and then concentrated under vacuum. The residue was re-dissolved in dichloromethane and n-heptane and concentrated again to afford the title compound as a solid. (113 mg, 82%).
