Diisopropylethylamine → N-(4-bromo-2-cyanophenyl)pyridine-2-carboxamide

Participants

Reaction Steps

To a stirred solution of 2-amino-5-bromobenzonitrile 2-1 (2.8 g, 0.014 moles) in toluene was added (4.95 mL, 0.028 moles) of N,N-diisopropylethylamine, followed by slow addition of (2.74 g, 0.015 moles) picolinoyl chloride. The mixture was stirred until complete by TLC. Reaction was filtered and dried under vacuum to afford 3 grams of 2-2. Analytical LCMS: (CH3CN/H2O/1% TFA, 4 min gradient), 95% pure, M+1 peak m/e 301.
