Reaction Steps
13.7 g phenyl-p-tolyl-chloroacetic acid methyl ester (prepared from p-tolyl-magnesium bromide and benzoyl-formic acid methyl ester and treatment with PCl5 ; (b.p. 150°C./0.3 mm Hg) are heated with 10 g imidazole in 100 ml acetonitrile at boiling temperature for 16 hours. The acetonitrile is distilled off in a vacuum. The residue is treated with 50 ml of water and then extracted with methylene chloride. The methylene chloride solution is distilled off in a vacuum and the residue recrystallized from a little ethyl acetate. The phenyl-p-tolyl-imidazolyl-acetic acid methyl ester i.e. phenyl-4-methylphenyl-imidazolyl-acetic acid methyl ester of m.p. 146°C. is thus obtained.
