Abstract

Purpose: An improved and economical method has been described for the synthesis of ERLOTINIB hydrochloride, as a useful drug in treatment of non-small-cell lung cancer.Methods: ERLOTINIB hydrochloride was synthesized in seven steps starting from 3, 4-dihydroxy benzoic acid. In this study, we were able to modify one of the key steps which involved the reduction of the 6-nitrobenzoic acid derivative to 6-aminobenzoic acid derivative. An inexpensive reagent such as ammonium formate was used as an in situ hydrogen donor in the presence of palladium/charcoal (Pd/C) instead of hydrogen gas at high pressure.Results: This proposed method proceeded with 92% yield at room temperature. Synthesis of ERLOTINIB was completed in 7 steps with overall yield of 44%.Conclusion: From the results obtained it can be concluded that the modified method eliminated the potential danger associated with the use of hydrogen gas in the presence of flammable catalysts. It should be mentioned that the catalyst was recovered after the reaction and could be used again.
