The triazole derivative 2 was prepared from 2-[(2-isopropyl-5-methylphenoxy)acetyl]-N-phenylhydrazine carbothioamide (1) by heating under reflux with aqueous NaOH [1,2]. 1 (1.0 g, 2.80 mmol) was suspended in aqueous NaOH (15 ml, 8%) and heated under reflux for 5 hours. The reaction mixture was treated with charcoal and filtered. The filtrate was cooled to room temperature and acidified carefully with dilute acetic acid (10%). The precipitate thus formed was filtered, washed with copious amount of water and recrystallized from ethanol to give 2 as white crystals (0.81 g, 85%).
