| titleOfInvention | Process for producing alkyl aryl ketone derivatives |
| abstract | PROBLEM TO BE SOLVED: To provide a simple production method capable of obtaining an alkyl aryl ketone derivative useful as a pharmaceutical such as a phosphodiesterase (PDE) -IV inhibitor or a synthetic intermediate thereof in high yield. [Solution] Embedded image (In the formula, R 1 represents such lower alkoxy, R 4 is a lower alkyl, X 1, X 2 and X 3 represents a halogen same or different, n represents an integer of 1 to 3, R 2 And R 3 are the same or different and each represents a hydrogen atom or the like) By reacting the compound represented by the general formula (I) with the compound represented by the general formula (II) in the presence of a base such as an alkali metal carbonate, the compound is represented by the general formula (III). Obtaining a compound and reacting the compound represented by the general formula (III) with the compound represented by the general formula (IV), the alkyl aryl ketone represented by the general formula (V) A method for producing a derivative is provided. [Selection figure] None |
