Yield:473895-88-4 85%
Reaction Conditions:
with sodium hydroxide
Steps:
2 Catalytic Air Dehydrogenation of 6-Hydroxymethyl-methyl-quinoxaline With 5% PD/C
The extracts were combined with the yellow solution of bromomethyl-quinoxaline and vacuum dried to give a yellow solid (1.92 g). This solid was then reacted with 30 ml of a 1.7 M solution of sodium hydroxide to give a solution of 6-hydroxymethyl-quinoxaline that was catalytically oxidized (0.2 g 5% Pd/C) with air at 85-95° C. for 48 hours. The black suspension was filtered to give an amber solution that was neutralized with dilute sulfuric acid to give a yellow powder (1.28 g, 85% yield) that precipitated from solution (6-quinoxaline carboxylic acid).
