Dimethylformamide → 4-[3-Chloro-5-(1-chloroethyl)-6-methoxy-2-methylphenyl]pyridine-2-carbonitrile

Participants

Reaction Steps

A mixture of cyanuric chloride (170 mg, 0.94 mmol) and N,N-dimethylformamide (73 μL, 0.94 mmol) was stirred at room temperature for 10 minutes and then a solution of 4-[3-chloro-5-(1-hydroxyethyl)-6-methoxy-2-methylphenyl]pyridine-2-carbonitrile (190 mg, 0.628 mmol) in methylene chloride (4 mL) was added and the reaction was stirred at room temperature overnight. The mixture was diluted with methylene chloride, washed with sat. NaHCO3, water, brine, dried over Na2SO4, filtered and concentrated. The crude product was used directly in the next step without purification (121 mg, 60%). LCMS calculated for C16H15Cl2N2O (M+H)+: m/z=321.0; Found: 321.0
