Bromoacetonitrile → HCID 86663245, compound

Participants

Reaction Steps

To a stirred solution of 3-amino-5-fluoro-4-methyl-benzoic acid, ethyl ester (Example 169b, 1.2 g) in THF (10 mL) at room temperature was added N-ethyldiisopropylamine (1.28 mL) followed by bromoacetonitrile (0.51 mL) and the reaction was heated at reflux for 14 h. Additional bromoacetonitrile (0.21 mL) was added and the mixture was heated at reflux for 6 h. Further bromoacetonitrile (0.21 mL) was added and heating was continued for a further 12 h. After cooling to room temperature the reaction was concentrated. Aqueous HCl (30 mL, 1N) and ethyl acetate (30 mL) were added. The layers were separated and the organic fraction was dried (Na2SO4), filtered and concentrated to give the subtitle product (1.43 g) as a solid.
