Synthesis of 1,3‐diaryl‐2‐propen‐1‐one oxime via the condensation of 1,3‐diaryl‐2‐propen‐1‐one with hydroxylamine hydrochloride in the presence of anhydrous sodium sulfate was carried out in refluxing EtOH for 2–4 h in 83%–93% yields. The significant features of the present procedure include higher yield, shorter reaction time, reduced molar ratio of hydroxylamine hydrochloride to substrate, compared to the reported literature method.
