Steps:

General experimental procedure for the hydroxylation ofquinoxalin-2(1H)-ones

General procedure: To a solution of quinoxalin-2(1H)-ones 1 (0.3mmol) and propane-1-thiol 2b (0.6 mmol) in CH3CN (1.5 mL) was addedg-C3N4 (10 mg). The reaction mixture was stirred under an ambient airatmosphere upon irradiation of 6 W blue LED lamps (445-450 nm) forabout 12h. After completion of the reaction, dichloromethane (10 mL)was added to the reaction mixture, g-C3N4 was filtered out of the mixture. Then, filtrate was concentrated in vacuo and the residue was purifiedthrough washing using a mixture solvent that consists of 10 mL ofpetroleum ether and 2 mL of ethyl acetate, followed by filtration anddrying to give solid product 3.
