Nitrogen-containing heterocyclic compound and method for producing same |
摘要 |
There are provided a nitrogen-containing heterocyclic compound such as a substituted amino-pyridine-N-oxide compound represented by formula (1), which is useful as a synthetic intermediate for an agrochemical and the like; and a method for producing the nitrogen-containing heterocyclic compound. (In formula (1), R1 and R2 each represents a hydrogen atom or an unsubstituted or substituted alkyl group; R3 represents a hydrogen atom, an unsubstituted or substituted alkylcarbonyl group or the like; R4 represents an unsubstituted or substituted alkylcarbonyl group, an unsubstituted or substituted arylcarbonyl group or the like; A represents a hydroxyl group, a thiol group or the like; m represents any one of integers of 1 to 4; k represents any one of integers of 0 to 3; and k+m≦4.); |

1. A substituted amino-pyridine-N-oxide compound represented by formula (1): in formula (1), 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, R3 represents a hydrogen atom, an unsubstituted or substituted alkylcarbonyl group, an unsubstituted or substituted arylcarbonyl group, or an unsubstituted or substituted alkoxycarbonyl group, R4 represents an unsubstituted or substituted alkoxycarbonyl group, m represents any one of integers of 1 to 4, and with the proviso that 2-ethoxycarbonylamino-6-methylpyridine-N-oxide is excluded. |
