| titleOfInvention | New method for producing pyrazine derivative |
| abstract | (57) [Summary] (Modified) [Purpose] 2 which is extremely useful as an intermediate for pyrazine derivatives having an inhibitory effect on superoxide anion -Providing a new and extremely effective process for producing benzyloxy-6-hydroxymethyl-3-isobutyl-5-methoxypyrazine-4-oxide. [Structure] A compound represented by the general formula (1) is reacted with an alkyl nitrite in the presence of copper halide to obtain a compound represented by the general formula (2), which is reacted with a metal methoxide to give a compound represented by the general formula: After preparing the compound represented by (3), A method for producing a compound represented by the general formula (4), which comprises reducing with a metal-hydrogen complex compound. [In the formula, R represents an alkyl group having 1 to 5 carbon atoms, Bn represents a benzyl group, and X represents a halogen atom. ] |
