Abstract
A method by which an intermediate product of an azole derivative can be produced at a lower cost and in a higher yield than those of known production methods is realized. A method of producing a compound of General Formula (III) includes: producing the compound of General Formula (III) by allowing a cyanide compound to act on a ketone derivative of General Formula (II); and washing the compound of General Formula (III) produced in the producing the compound of General Formula (III) with an alkaline aqueous solution.
Claims2
A method of producing a compound represented by General Formula (III),
- where R3 and R4 are each independently hydrogen, halogen, a C1-C6-alkyl group, a C1-C6-alkoxy group, a C1-C6-haloalkyl group, or a C1-C6-haloalkoxy group;
- m is an integer from 0 to 5, and when m is 2 or greater, a plurality of R4 moieties may be different from each other;
- and
- n is an integer from 0 to 4, and when n is 2 or greater, a plurality of R3 moieties may be different from each other;
- the method comprising:
- producing the compound represented by General Formula (III) by allowing a cyanide compound to act on a ketone derivative represented by General Formula (II), and
- washing the compound represented by General Formula (III) produced in the producing the compound represented by General Formula (III) with an alkaline aqueous solution;
- where X is a halogen atom, and
- R3, R4, m, and n in Formula (II) are respectively identical to R3, R4, m, and n in Formula (III).
