<p><P>PROBLEM TO BE SOLVED: To provide a method for preparing an N-(2-aminoethyl)azole compound, which is a preparation method offering short reaction time, high purification efficiency of a final product, high production efficiency and high safety because a reaction solution undergoes no heat generation or rise of liquid level caused by bubbling. <P>SOLUTION: The method for preparing the N-(2-aminoethyl)azole compound comprises reacting an azole-based compound (A) and an ethylamine derivative (B) having a leaving group at position 2 in the presence of a base (C) in a solvent (D) so as to prepare the N-(2-aminoethyl)azole compound. Here, the ethylamine derivative (B) having the leaving group at position 2 is fed to the reaction system in portions while the reaction system is maintained at 50-200°C. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
