Abstract:
PURPOSE: A 5-membered hetero aryl-substituted phthalazinone derivative and a pharmaceutical composition containing the same are provided to prevent or treat MCH receptor-1-associated diseases. CONSTITUTION: A 5-membered hetero aryl-substituted phthalazinone derivative is denoted by chemical formula 1. In chemical formula 1, a to e are each C(carbon), N(nitrogen), S(sulfur) or O(oxygen). A method for preparing 5-membered hetero aryl-substituted phthalazinone derivatives comprises: a step of a compound of chemical formula 2 with piperidine compounds of chemical formula 3 under the presence of organic solvent and base by alkylation. A pharmaceutical composition for preventing or treating MCH receptor-1-associated diseases contains the derivatives and pharmaceutically acceptable salt thereof as an active ingredient.
Abstract:
PURPOSE: A phthalazinone derivative containing an aryl piperidine group and a pharmaceutical composition containing the same are provided to prevent or treat MCH-associated diseases. CONSTITUTION: A phthalazinone derivative containing an aryl piperidine group is denoted by chemical formula 1. A method for preparing the derivative comprises a step of alkylating a compound of chemical formula 2 with a piperidine compound of chemical formula 3 under the presence of organic solvent and base. The organic solvent ether solvent, low alcohol of C1-C4, DMF(dimethyl formamide), DMSO(dimethyl sulfoxide, acetonitrile or water. The base is an organic base including pyridine, triethyl amine, N,N-diisopropyl ethyl amine(DIPEA), 1,8-diazabicylco[5.4.0]-undecene(DBU); or an inorganic base including sodium hydroxide, sodium carbonate, potassium carbonate, cesium carbonate, and sodium hydride.
