Triethylamine → 6-{(SR)-1-[(3RS,4SR)-1-(4-Cyano-piperidine-1-carbonyl)-4-(3,4-dichloro-phenyl)-pyrrolidin-3-yl]-ethoxy}-nicotinonitrile

Participants

Reaction Steps

To a stirred solution of (3RS,4SR)-3-[(SR)-1-(5-Cyano-pyridin-2-yloxy)-ethyl]-4-(3,4-dichloro-phenyl)-pyrrolidine-1-carbonyl chloride (30 mg, 0.070 mmol) in CH2Cl2 (4 mL) were added Et3N (0.015 mL, 0.11 mmol) and piperidine-4-carbonitrile (commercially available) (9 mg, 0.084 mmol). Stirring was continued overnight, and the reaction mixture was concentrated under vacuo and directly purified by flash chromatography (SiO2, EtOAc) to yield 24 mg (69%) the title compound as light yellow oil. ES-MS m/e: 498.0 (M+H+).
