Reaction Steps

Ethylene chlorohydrin (20.2 g, 0.25M) was added to a solution of 2-hydroxy-3-phenyl-5,6-dimethyl-pyrazine (10.0 g, 50 mM) and 5N NaOH (50 ml) in t-butanol (150 ml), and stirred at 60° C. for 2.5 hours. Water was added to the reaction mixture, the mixture extracted with chloroform, and the extract dried with anhydrous sodium sulfate and concentrated in vacuo. The residue was charged on a column of silica-gel (C-200, 130 g) packed with chloroform and eluted with chloroform-methanol (100:1) to obtain compound 109 (8.73 g, yield: 71.5%).
