| titleOfInvention | Process for the preparation of 2-Hydroxy-N-(2-hydroxyethyl)-3-methoxy-5-(2-propenyl)benzamide |
| abstract | The present invention is an alkyl 5-allyl-2-hydroxy-3-methoxy benzoate used as a key intermediate of alibendol and 2-hydroxy-N- (2-hydroxyethyl) -3-methoxy- The present invention relates to a method for preparing 5- (2-propenyl) benzamide (alibendol), and to a method for preparing alkyl 5-allyl-2-hydroxy-3-methoxy benzoate and alibendol using the same. In particular, in preparing 2-hydroxy-N- (2-hydroxyethyl) -3-methoxy-5- (2-propenyl) benzamide, alkyl 5-allyl-2-hydroxy-3 Reacting methoxy benzoate with allyl bromide in the presence of an organic or inorganic base to easily produce the corresponding allyl ether, which is then reacted with ethanol amine in high yield of 2-hydroxy-N- A method for producing (2-hydroxyethyl) -3-methoxy-5- (2-propenyl) benzamide.n n n n n n n n In the formula, R is an alkyl group having 1 to 9 carbon atoms (except for ethyl group). |
