PROBLEM TO BE SOLVED: To provide a method for stably supplying 2,5-bis (aminomethyl) furan. When synthesizing 2,5-bis (aminomethyl) furan by hydrogenation of furan-2,5-dioxime, hydrogen equivalent of 2 or more equivalents is added in advance to generate hydrogen. The hydrohalic acid reacts simultaneously with the formation of 2,5-bis (aminomethyl) furan dihydrohalate with high selectivity, and a base is added to the dihydrohalide. Thus, diamine can be easily supplied. [Selection figure] None |
