The present invention is directed to a method for producing a cyclic diamine compound (3) or a salt thereof through the following scheme:
(wherein Ar represents a phenyl group, a pyridyl group, or a pyrimidinyl group, any of which may have a substituent; X represents NH, S, or O; ring A represents a benzene ring or a pyridine ring, which may have a substituent; 1 represents an integer of 1 or 2; m represents an integer of 1 or 2; and n represents an integer of 1 to 6). The method enables synthesis of a cyclic diamine compound (3) or a salt thereof, which serves as an ACAT inhibitor, in an industrially useful manner.
本发明涉及通过以下方案制备环状二胺化合物(3)或其盐的方法:(其中Ar代表苯基、
吡啶基或
嘧啶基,任何一个可能有取代基;X代表NH、S或O;环A代表苯环或
吡啶环,可能有取代基;1表示1或2的整数;m表示1或2的整数;n表示1到6的整数)。该方法能够以工业上有用的方式合成环状二胺化合物(3)或其盐,其作为ACAT
抑制剂。
