    摘要： The present invention relates to an industrially preferable process for producing an indolopyrrolocarbazole derivative represented by the formula (I): or a pharmaceutically acceptable salt thereof, which is useful as an anti-cancer agent. The above process comprises treating a compound represented by the formula (V): or a pharmaceutically acceptable salt thereof, a solvate thereof or a salt thereof, with a base in an inert solvent, followed by treatment with an acid, and further treating the resulting reaction solution with a base in an inert solvent and subsequently with an acid, and then reacting the resulting compound with an acid addition salt of hydrazine diol in the presence of an acid scavenger, followed by removal of protecting group(s) from the resulting compound.

    摘要： A method by which a halogen atom of a halogen compound can be efficiently replaced with an electrophilic group.Also provided are: a reagent for converting a functional group through a halogen-metal exchange reaction, characterized by comprising either a mixture of a magnesium compound represented by the formula R1—Mg—X (I) (wherein R1 represents a halogen atom or an optionally substituted hydrocarbon residue; and X1 represents a halogen atom) and an organolithium compound represented by the formula R2—Li (II) (wherein R2 represents an optionally substituted hydrocarbon residue) or a product of the reaction of the magnesium compound with the organolithium compound; and a process for producing with the reagent a compound in which a halogen atom of a halogen compound has been replaced with an electrophilic group.
