Abstract: An improved and scalable method is developed for the synthesis of 7-ethyltryptophol, a key intermediate for Etodolac, a non-steroidal anti-inflammatory drug (NSAID) starting from commercially available 2-ethylphenyl hydrazine and dihydrofuran with H<sub>2</sub>SO<sub>4</sub> as a catalyst in <i style="mso-bidi-font-style:normal">N</i>,<i style="mso-bidi-font-style:normal">N</i>-dimethylacetamide (DMAc)-H<sub>2</sub>O (1:1) as a solvent in 69% yield. The method is easy, inexpensive and reproducible and the process is clean, high yielding and operationally simple.
