Author(s): Pailla Umareddy, Veera Reddy Arava

Benzo[b]furan and Benzo[b]thiophene-3-acetic acids are prepared from the corresponding phenol or thiophenol by reacting with ethyl 4-chloro acetoacetate. The isolated acetoacetic ester derivatives were cyclized to give the respective ester of 3-acetic acids in good yields. Final hydrolysis resulted in 3-acetic acids in high yields.
