Reaction Steps
Corresponding to J. Org. Chem. 40 (1975) 3497, 16.7 g of 2-methoxyphenylacetonitrile, 158 ml of lithium triisopropyl-amide (2 mol solution) and 46.7 ml of 1,2-dichloroethane in 96 ml of tetrahydrofuran and 58.6 ml of hexamethylphosphoric acid triamide are reacted with one another. 5.6 g of 1-(2-methoxy-phenyl)-cyclopropyl-carbonitrile, boiling point 104-115° C./0.1 mbar, which was also reacted as described for 3-(1-phenyl-cyclobutyl)-2-oxo-propionic acid, is obtained. 3-[1-(2-Methoxyphenyl)-cyclopropyl]-2-oxo-propionic acid is thus obtained as an oil.
