Methyl homoveratrate

A) Methyl Homoveratrate.—In a 3-I. round-bottomed flask are placed 1 1. of 10 per cent sodium hydroxide solution and 200 g. (0.65 mole) of the azlactone of a-benzoylamino-/i-(3,4-dimethoxyphenyl) acrylic acid (m.p. 149-150°) (Org. Syn. 13, 8). The flask is fitted with a reflux condenser and immersed in an oil bath so that the inner level is lower than the oil level of the bath (Note 1). The mixture is refluxed gently for six to seven hours, until the evolution of ammonia is complete. The resulting solution contains the sodium salts of 3,4-dimethoxyphenylpy-ruvic acid (Note 2) and benzoic acid. [Pg.31]

Homoveratric acid has been prepared by the methylation of homoprotocatechuic acid1 and of homovanillic acid2 with methyl iodide, and from veratric aldehyde through the azlactone and 3,4-dimethoxyphenylpyruvic acid.3 The procedure given here is adapted from that last mentioned and from that used for the preparation of -methoxyphenylacetic acid.4...
