(E)-7-(3-pyridyl)-7-phenyl-6-heptenoic acid (Ia-4) (500 mg) and sodium hydrogen carbonate (160 mg) were added to water (5 ml) to make a homogeneous solution. The solution was concentrated under reduced pressure. The concentrate was pulverized by the use of ethanol-isopropylether to obtain sodium (E)-7-(3-pyridyl)-7-phenyl-6-heptenoate (Ii-76, 300 mg). The physico-chemical properties and other data of the product are shown in Table 6.
