1. A method for producing a compound represented by formula (13) comprising reacting a compound represented by formula (9) with a halogenating agent in a presence of a compound represented by formula (12), wherein each of R1 and R2 independently represents a hydrogen atom, or an unsubstituted or substituted alkyl group, and R1 and R2 may form a ring together, R6 represents an unsubstituted or substituted alkylcarbonyl group, an unsubstituted or substituted arylcarbonyl group, an unsubstituted or substituted heteroarylcarbonyl group, an unsubstituted or substituted alkoxycarbonyl group, an unsubstituted or substituted alkylsulfonyl group, or an unsubstituted or substituted arylsulfonyl group, R8 represents an unsubstituted or substituted alkylcarbonyl group, an unsubstituted or substituted arylcarbonyl group, or an unsubstituted or substituted alkoxycarbonyl group, A represents a hydroxyl group, a thiol group, an amino group, a nitro group, a halogen atom or an organic group, m represents any one of integers of 1 to 4, k represents any one of integers of 0 to 3, wherein k +m 4, X represents a halogen atom, and X1 represents a chlorine atom or a bromine atom. |
