Coumarin derivatives, process for preparing the same and pharmaceutical composition comprising the same |
| abstract |
PURPOSE: A coumarin derivative and a pharmaceutical composition containing the same are provided to treat or prevent various diseases such as senile dementia. CONSTITUTION: A coumarin derivative is denoted by chemical formula I. In chemical formula I, n is integer from 0 to 4; R is NR1R2; R1 and R2 are independently hydrogen or alkyl group of C1-C6. A method for preparing the coumarin derivative of chemical formula I or pharmaceutically acceptable salt thereof comprises: a step of coupling a compound of chemical formula 1 and a compound of chemical formula 2 to prepare an intermediate compound of chemical formula 3; a step of deprotecting the intermediate compound of chemical formula 3. |
