[Problems to be Solved by the Invention] All of the above-mentioned compounds have a strong vasodilatory effect, but their effects on blood clots, which are a cause of cerebral and cardiac circulation disorders, cannot be said to be sufficient. Therefore, it has been desired to develop a compound that not only has a vasodilatory effect but also has a platelet aggregation inhibiting effect, and to develop an industrial method for producing the compound. [Means for Solving the Problems] Under such circumstances, the present inventors conducted intensive research and found that the carboxyl group of a conventionally known 1,4-dihydropyridine derivative has the general formula

[Formula] "In the formula, R 4 and R 5 each have the same meaning as above." A compound of the general formula R 3 -CHO (XII) "In the formula, R 3 has the same meaning as above." It can be obtained, for example, by reacting with a compound having the meaning of "" under the conditions described in Tetrahedron, Vol. 28, p. 663 (1972). Examples are given below to explain the present invention in more detail, but the present invention is not limited thereto. Example 1 (1) 6.5 g of (E)-3-[4-(pyridin-3-ylmethyl)phenyl]-2-methylacrylic acid ethyl ester was dissolved in 33 ml of anhydrous tetrahydrofuran, and hydrogenated under ice cooling. Add 660 mg of lithium aluminum little by little over 1 hour. After reacting for 1 hour under ice-cooling and further at room temperature for 2 hours, 30 ml of ethyl acetate and 5 ml of water were added under ice-cooling.
Add ml little by little. Insoluble matter was filtered off, dried over anhydrous magnesium sulfate, the solvent was distilled off under reduced pressure, and the resulting residue was subjected to column chromatography [Wako Silica Gel C-200, elution solvent; benzene: ethyl acetate ( Capacity ratio 2:1)]

was dissolved in 16 ml of methylene chloride, and 3.64 ml of thionyl chloride was added dropwise thereto under ice cooling, followed by reaction under heating and reflux for 1 hour. When the solvent and excess thionyl chloride are distilled off under reduced pressure, (E)-3-[4-(pyridin-3-ylmethyl)
phenyl]-2-methylallyl chloride hydrochloride is obtained. This is dissolved in 8 ml of N,N-dimethylformamide. (2) Add potassium tert. to 40ml of ethylene glycol.
- 11.3 g of butoxide are added in portions at room temperature while stirring. After adding the N,N-dimethylformamide solution obtained in (1) dropwise to this solution at the same temperature,
Incubate at ℃ for 1 hour. Then, add water under ice-cooling.
Add 400ml, adjust the pH to 7 with 6N hydrochloric acid, and then extract with 200ml of ethyl acetate. The extract is washed successively with 200 ml of water and 100 ml of saturated saline, and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, and the resulting residue was purified by column chromatography [Wako silica gel C-200, elution solvent: benzene:ethyl acetate (volume ratio 1:2)] to obtain 2 as a colorless oil. -[(E)-3-[4-(pyridin-3-ylmethyl)phenyl]-2-methylallyloxy]ethanol 2.65g (yield 56.0
