| titleOfInvention | Method for producing thienyl ether derivative |
| abstract | (57) [Summary] [Structure] The following general formula (1), (In the formula, R 1 represents a hydrogen atom, an alkoxycarbonyl group, etc., and R 2 represents a cyano group, an alkoxycarbonyl group, etc.), a basic alkali metal aqueous solution and a dialkyl sulfuric acid are hydrogen ions. The reaction is carried out in a concentration range of 6-11. [Effect] This is a production method in which water is basically used as a reaction solvent, and alkali sulfate of a by-product inorganic substance is dissolved in water. Therefore, the thienyl ether derivative can be obtained with good selectivity and high yield, without the need to perform the filtration operation of the by-product inorganic substance. |
