According to these documents, the target pyrimidine derivative ⁇ pyrazole derivative is converted from 1,1,3,3-tetramethoxypropane 1,1,3,3-tetratetraethoxypropane This is obtained.
- ethyl ethyl orthoformate and the corresponding ethyl vinyl ether are used, but the ethyl vinyl ether has a special flash with a boiling point of 36 to 37 ° C. It is industrially difficult to use in large quantities, like methyl vinyl ether.
- 1,1,3,3-Tetramethoxypropane and 1,1,3,3-Tetraethoxypropane which are useful as skeletal forming agents, are disclosed in, for example, Japanese Patent Publication No. 57-1588735.

- 1,1,3,3-tetraethoxypropane is used for the synthesis.
- ethyl ethyl orthoformate and the corresponding ethyl vinyl ether are also useful as skeletal forming agents.
- 1,3,3-triethoxy_ 1 For the production of monomethyl ether and 1,3,3-trimethoxy-1-ethyl ether, the use of methyl vinyl ether or ethyl vinyl ether is also essential.
- the present invention relates to the production of 1,1,3,3-tetraalkoxypropane using industrially available vinyl ether when producing 1,1,3,3-tetraalkoxypropane.
- the purpose is to do.
- Another object of the present invention is to provide a method capable of industrially producing a tetraalkoxypropane derivative such as a virazole derivative / pyrimidine derivative, which is an intermediate for medical and agricultural chemicals.

- the present inventors are highly skeletal forming agents having high reactivity.For example, they are used as raw materials for tetrazolepropane derivatives such as pyrazole derivatives and pyrimidine derivatives, which are intermediates for pharmaceuticals and agrochemicals. Research on the purpose of synthesizing tetraalkoxypropane from industrially available butyl ether. The use of propoxy vinyl ether, which has a relatively high boiling point, eliminates the disadvantages described above and is new and asymmetric.
- 1,3,3-trimethoxy 1- (n- or iso-) propoxypropane and 1,3,3-triethoxy 11- (n- or iso-) propoxypropane The authors found that 1,1,3,3-tetramethoxypropane and 1,1,3,3-tetraethoxypropane could be synthesized using diether. It was completed a light. Furthermore, they have found that tetraalkoxypropane derivatives such as virazole derivatives and pyrimidine derivatives can be easily synthesized using these mixed biel ethers, and completed the present invention.
- the present inventors reacted orthoformate with propylbutyl ether for the purpose of synthesizing a novel and asymmetric 1,3,3_trialkoxy-1-propoxypropane, and obtained the intended product.
- the new, asymmetric 1,3,3-trialkoxy-1-propoxypropane is then converted to 1,1,3,3-tetraalkoxypropane by an alkoxy exchange reaction with the above product. Conceivable.
- the ratio of the symmetric and asymmetric products is determined by the molar ratio of the starting materials, propoxybutyl ether and trialkyl orthoformate. It can be adjusted arbitrarily by changing the ratio and the reaction temperature. For example, in a system in which orthoformate is used in a large excess, a symmetric isomer is preferentially formed, and also from the viewpoint of the yield, the butyl ether can be effectively used. An excess amount of orthoformate can be recovered and reused.
- propyl vinyl ether is placed in a glass flask and heated, and then a Lewis acid compound such as anhydrous iron (III) chloride, boron trifluoride or the like is used as a reaction catalyst, and vinyl ether 100 parts by weight is used. About 0.5 to 2.0 parts, and with stirring, about 1.0 to 1.3 moles of an orthoester such as methyl orthoformate per mole of vinyl ether is added. React at a temperature of about 30 ° C to about 50 ° C.
- a Lewis acid compound such as anhydrous iron (III) chloride, boron trifluoride or the like
- reaction mixture is distilled under reduced pressure, whereby the present invention 1,3,3—Trialkoxy-1 1-propoxypropane, which is a new compound, is distilled off, followed by 1,1,3,3—tetraalkoxypropane.
- a butyl ether which is a raw material for synthesizing a tetraalkoxypropane, which is a skeleton-forming agent, is used as propoxyvinyl ether or butoxyvinyl ether, which can be used industrially.
- 1, 1 1, 1
- propoxyvinyl ether or butoxyvinyl ether and trialkyl orthoformate are reacted in the presence of a Lewis acid catalyst ⁇ to produce tetraalkoxypropane.
- a Lewis acid catalyst ⁇ examples include trimethyl orthoformate, triethyl orthoformate, triformate ( ⁇ - or is ⁇ _) propyl, and tri-orthoformate (n- or iso-) butyl.
- the use of trimethyl orthoformate is more preferable in terms of availability.
- the amount used is about 1 to 10 mol per 1 mol of butyl ether.
- the oleic acid examples include boron trifluoride, boron trifluoride etherate, aluminum chloride (III), tin chloride (II), hydrogen fluoride, mercuric chloride, and iron chloride (III).
- iron (III) chloride is preferred from the viewpoints of safety, corrosiveness and operability.
