PURPOSE: To readily and industrially advantageously obtain the title compound useful as an intermediate for medicinal production in high selectivity and high yield by reacting a specific ether compound with an azole compound having a specific azole ring under an acidic condition.

CONSTITUTION: A noncyclic ether compound expressed by formula I (R1 and R2 are organic residues), preferably a compound expressed by formula II (R3 and R5 are R1 and R2; R4 is H, R1 or R2) is reacted with an azole compound having an azole ring in which N number is 2-4, preferably in a solvent and atmosphere such as N2 gas in the presence of an acid catalyst such as p- toluenesulfonic acid pyridinium salt under an acidic condition and at an ambient temperature to 150°C to provide the objective compound expressed by formula III (A is monovalent group having a free electronic charge on N atom of azole ring in the above-mentioned azole compound), preferably a compound expressed by formula IV, useful as an intermediate for producing an amide compound having an azole ring used for a medicine in drug design.
