Title:
METHOD FOR PRODUCING PHENOLIC COMPOUND
Document Type and Number:
WIPO Patent Application WO/2015/198850
Kind Code:
A1
Abstract:
Provided is a method for producing a compound represented by formula (2-b), which is useful as an intermediate for producing agricultural chemicals. The method includes a step for obtaining a compound represented by formula (2-a) by oxidizing the compound represented by formula (1) with hydrogen peroxide in the presence of sulfuric acid and/or a C1–6 alkanesulfonic acid that may be halogen-substituted and in the presence of a C2–12 aliphatic carboxylic acid and/or sulfolane. The method also includes a step for obtaining a compound represented by formula (2-b) by nitrating a compound represented by formula (2-a) in the presence of sulfuric acid and/or a C1–6 alkanesulfonic acid that may be halogen-substituted.
