The Comparison of Two Synthetic Methods of dl-Naproxen via 1.2-Aryl Rearrangement

Two synthetic methods of dl-naproxen via 1. 2-Aryl rearrangement were compared. Naproxen was obtained in high yield when ZnO was used as catalyst and in middle yield when KOAC was used. The modified procedures were made in bromination and rearrangement. T
