Abstract:
PURPOSE: A novel imidazolylalkylcarbonyl derivative which is effective as calcium ion channel regulator is provided to effectively block T-type calcium ion channel, prevent and treat brain diseases, heart diseases and pain. CONSTITUTION: An imidazolylalkylcarbonyl derivative is denoted by chemical formula 1. The imidazolylalkylcarbonyl derivative of chemical formula 1 is prepared by performing amide bond of piperazine derivative of chemical formula 3 with imidazolylalkylcarboxylic acid of chemical formula 2. The amide bond is performed using binder selected from phosphonium system, ammonium system, carbodiimide system, imidazolinium, and organic phosphine system. A method for preparing the imidazolylalkylcarboxylic acid of chemical formula 2 comprises: a step of performing hetero-michael addition reaction of ethy alkenoate with imidazole compound under the presence of KF/Al2O3 catalyst to produce ethoxycarbonylalkylimidazole compound of chemical formula 2a; and a step of hydrolyzing the ethoxycarbonylalkylimidazole compound of chemical formula 2a to prepare imidazolylalkylcarboxylic acid of chemical formula 2.
