A DEVELOPED PROCESS FOR THE SYNTHESIS OF 2-ETHYL PHENYL HYDRAZINE HYDROCHLORIDE, A KEY STARTING MATERIAL FOR 7-ETHYL TRYPTOPHOL

A developed process for the synthesis of 2-ethyl phenyl hydrazine hydrochloride, a key starting material for 7-ethyl tryptophol. Starting from commercially available 2-ethylaniline. First prepared a diazonium salt of aniline by using HCl and sodium nitrite at lower temperature and then reduced the diazonium salt with sodium sulfite and Cons. H2SO4 within 92% yield. The method is easy, inexpensive, without purification getting pure solid. The process is very clean,high yielding & high quality and operationally simple
