N,N-Dimethylaniline → HCID 23110951, compound

Participants

Reaction Steps

3-Amino-2-[(2-methoxyethyl)oxy]-6-methyl-4-[(2,2,2-trifluoroethyl)oxy]pyridine (1.39 g, 4.96 mmol) was dissolved in dichloromethane (15 mL). N,N-dimethylaniline (0.76 g, 6.27 mmol) was added to the solution. Under stirring on an ice bath, bromoacetyl bromide (1.16 g, 5.75 mmol) in dichloromethane (5 mL) was added dropwise to the mixture, followed by stirring at the same temperature for 30 minutes. The reacion mixture was directly subjected to silica gel column chromatography (eluent: n-hexane/ethyl acetate=5/1→n-hexane/acetone=1/1) for purification, to thereby yield 2-bromo-N-[2-[(2-methoxyethyl)oxy]-6-methyl-4-[(2,2,2-trifluoroethyl)oxy]pyridin-3-yl]acetamide as a colorless solid (1.98 g, 99%).
