METHOD FOR PRODUCING INHIBITOR OF ACTIVATED BLOOD COAGULATION FACTOR X (FXA)

摘要

The present invention addresses the problem of providing a novel method for producing a compound that can act as an FXa inhibitor, a salt of the compound or a hydrate of the compound or the salt. The solution for the problem is a method for producing a compound represented by formula (X) or the like, said method being characterized by employing a production method in which the above-mentioned compound or the like is produced with starting from a compound represented by formula (1-x) or the like through a compound represented by formula (1-1) or the like. [In the formulae, X represents a halogen atom or the like; and R1 represents a phenyl group which may have a substituent.]
