PRODUCTION METHOD OF 2,6-DIHALOPURINE

By reacting the compound of the formula [Ia] or [Ib] with halosilane compound and an agent for diazo reaction, 2,6-dihalopurine of the formula [II] can be produced conveniently in a high yield and can be easily isolated.wherein each symbol is as defined in the specification.

Process for producing 2,6-dihalogenopurine

A process for conveniently and efficiently preparing a 2,6-halogenopurine using an inexpensive starting material. A process for preparing a 2,6-dihalogenopurine, comprising treating a 2-amino-6-halogenopurine having a protective group at 7th position or 9th position with a diazotizating agent and a halogen source; and a process for preparing a 9-acyl-2-amino-6-halogenopurine, comprising treating a 2-amino-6-halogenopurine with an acylating agent in the presence of a base.
