Reaction Conditions

Reaction Steps

Ethylene chlorohydrin (4.03 g, 50 mM) was added to a solution of 2-hydroxy-3-benzyl-5,6-dimethyl-pyrazine (2.14 g, 10 mM) and 5N NaOH (10 ml) in t-butanol (30 ml), and stirred at 60° C. for 2.5 hours. Water (100 ml) was added to the reaction mixture, and the mixture was extracted three times with chloroform, the extract dried with anhydrous magnesium sulfate and concentrated in vacuo. The residue was charged on a column of silica-gel (C-200, 25 g) and eluted with chloroform-methanol (100:1) to obtain compound 112 (2.22 g, yield: 86.0%).
