Diisopropylethylamine → N-((2-(3-chloro-4-fluorophenyl)-6-(trifluoromethyl)pyridin-3-yl)methyl)-2-(3-fluoro-4-(methylsulfonamidomethyl)phenyl)propanamide

Participants

Reaction Steps

To a stirred solution of (2-(3-chloro-4-fluorophenyl)-6-(trifluoromethyl)pyridin-3-yl)methanamine hydrochloride (1.104 g, 3.632 mmol) and 2-(3-fluoro-4-(methylsulfonamidomethyl)phenyl)propanoic acid (1 g, 3.632 mmol) in tetrahydrofuran (28 mL) was added 1-hydroxybenzotriazolhydrate (0.49 mL, 3.632 mmol), O-(1H-benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium tetrafluoroborate (1.166 g, 3.632 mmol) and N-ethyldiisopropylamine (1.852 mL, 10.896 mmol) and the reaction mixture was allowed to stir for 48 h. The reaction mixture was concentrated under reduced pressure and the solid obtained was purified by column chromatography (eluent:ethyl acetate/cyclohexane 2:1) to afford a white solid (example 16) (605 mg, 30%).
