Reaction Steps

Furthermore, a synthesis method of the hydroxy group-protecting agent 5 will be explained. To a 10 mL eggplant flask, 599.2 mg (1.50 m mol) of 2,4,6-tribenzyloxy-1,3,5-triazine, 5.00 mL of toluene and 38.8 mg (030 m mol) of iodine were added, heat-perfused, and reacted for 31 hours. After the reaction, 5 mL of an aqueous solution of saturated sodium thiosulfate was added, which was washed with 5 mL of 1 N sodium bicarbonate water, 5 mL of 1 N hydrochloric acid, 5 mL of water and 5 mL of saturated salt water. A resulting organic phase was dried by magnesium sulfate, from which the solvent was distilled away, and the residue was isolated and purified by silica-gel chromatography to obtain 126.2 mg of 1,3-dibenzyl-6-(benzyloxy)-1,3,5-triazine-2,4(1H,3H)-dione (yield: 21%).
