Abstract
PURPOSE: To obtain the titled compound useful as a raw material for agricultural chemicals and drugs in high yield, by reacting an unsaturated fatty acid with nitric acid to give a compound, reacting this compound with an acetic ester in the presence of a base, reusing the unsaturated fatty acid while recovering it.
CONSTITUTION: An unsaturated fatty acid shown by the formulaI(R1 and R2 are lower alkyl) is reacted with nitric acid to give a nitrated unsaturated fatty acid shown by the formula II, which is reacted with an acetic ester in the presence of a base (e.g., sodium hydride, potassium hydride) to give the desired compound. In the reaction, the unsaturated fatty acid shown by the formulaIis recovered and reused in the following reaction. The reaction of the nitrated unsaturated fatty acid with the acetic ester in the presence of the base is carried out at 10W200°C for 0.5W8hr. The recovered unsaturated fatty acid can be nitrated simply with nitric acid, and used repeatedly in the reaction, and this process is effective as an industrial one.
