摘要

Disclosed is a process for producing an amidine derivative having an ester bond, which is a compound highly useful as a substance having an anti-coagulation activity, on an industrial scale. Specifically disclosed is a process for producing an amidine compound (4), which comprises reacting an acid halide (1), either one of a compound (2) or a compound (5) and an amidine compound (3) with one another to form an ester bond, wherein the compounds (1) to (5) are represented by formulae (wherein each symbol is as defined in the description).
