A synthetic intermediate of a pentacene derivative that can be used as a material for an organic electronic device such as a light-emitting device, a photoelectric conversion device, and a semiconductor, and a method for producing the same. The present invention provides the following formula (I): [Wherein, R 1 to R 4 are a hydrogen atom, an alkyl group, and the like, A 1 to A 4 are an electron withdrawing group such as a hydrogen atom or an alkoxycarbonyl group, and at least one of A 1 to A 4 . One is an electron-withdrawing group. ], The manufacturing method, etc. are provided. A pentacene derivative can be obtained by reacting the pentacene quinone derivative with a Grignard reagent or an organolithium reagent. [Selection figure] None |
