| abstract |
A method for preparing a benzophenone derivative represented by the general formula: ** Formula ** wherein R2a represents an alkoxy group; and R3b represents a cycloalkyl group, or a salt thereof, comprising: subjecting a benzophenone derivative represented by the general formula: ** Formula ** wherein R3a and R4a represent an alkyl group, to a dealkylation reaction to provide a benzophenone derivative represented by the formula: ** Formula ** or a salt thereof, then subject the benzophenone derivative or a salt thereof to an alkylation reaction in the presence of a base to provide a benzophenone derivative represented by the formula general: ** Formula ** wherein R3b is defined as before, or a salt thereof, then subject the benzophenone derivative or a salt thereof to a ring opening reaction in the presence of a base to provide a benzophenone derivative represented by the general formula [1d]: ** Formula ** |
