| titleOfInvention | Processes For Preparing 1,1-di-(4-(dialkylamino)phenyl)ethylene Derivatives And Their Precursors |
| abstract | The present invention synthesizes the Grignard yard reagent from the 4-halo-N, N-dialkylaniline derivative represented by the following formula (II) and magnesium, and the synthesized Grignard yard reagent is represented by the alkyl acetate derivative represented by the following formula (III) 1,1-di- (4- (dialkylamino) phenyl represented by the following formula (I), characterized in that it comprises a step of synthesizing a carbinol and reacting with alkenization through dehydration of the carbinol. A method for preparing an ethylene derivative and a precursor thereof for a 4-halo-N, N-dialkylaniline derivative:n n n n n n n n n n n n n n n n n n Wherein R 1 , R 2 is a hydrogen atom, a lower alkyl group or a cycloalkyl group, R 3 , R 4 , R 5 is a lower alkyl group or a cycloalkyl group, and X is a chlorine atom, bromine atom or iodine atom. |
