Reaction Steps
Ethylene chlorohydrin (20.2 g, 0.25M) was added to a solution of 2-hydroxy-3-ethyl-5,6,7,8-tetrahydro quinoxaline (8.90 g, 50 mM) in dilute aqueous 5N NaOH (50 ml) and t-butanol (150 ml), and stirred at 60° C. for 3 hours. The t-butanol was distilled off in vacuo. Water was added to the residue, which residue was then extracted three times with chloroform, dried with anhydrous sodium sulfate and concentrated in vacuo. The residue was charged on a column of silica-gel (C-200, 170 g) packed with chloroform, and eluted with chloroform-methanol (100:1) to obtain compound 646 (9.30 g, yield: 83.8%).
