An azolylmethylidenehydrazine derivative represented by the formula (I)
wherein Ar is an aryl group optionally having substituent(s) or a heteroaryl group optionally having substituent(s), R
1
and R
2
are the same or different and each is an alkyl group, a cycloalkyl group, an aralkyl group optionally having substituent(s), an aryl group optionally having substituent(s), a heteroarylalkyl group optionally having substituent(s), or R
1
and R
2
are bonded to each other to form a nitrogen-containing heterocyclic group optionally having substituent(s), and X is CH or a nitrogen atom, or a pharmacologically acceptable salt thereof is useful as a medicament, particularly as an antifungal agent, or an anti-inflammatory agent or an antiallergic agent.

The classical Ullmann CS crosscoupling reaction of aryl iodides with aromatic/alkyl thiols under catalysis of 15 mol% Cu(OAc)2·H2O and 15 mol% 2,2′‐biimidazole works at 80°C in DMSO for 3 h to provide a variety of aryl sulfides in good to excellent yields.
