Procedure
K-t-BuO (2.1 g, 18.7 mmol) was added to a stirred solution of 1-phenyl-1-ethanol (2.45 g, 20.1 mmol) in dioxane (30 mL) at 0° C. (ice-bath). After 10 min of stirring, 2,6-dichloropyrazine (2.49 g, 16.7 mmol) was added whereupon the reaction mixture turned orange colored. After being stirrred for a further 1.5 h, ether was added and the mixture was filtered. Concentration in vacuo furnished an orange colored oil that was purified by silica gel chromatography (15×5 cm) using n-hexane ethyl acetate (9:1) as eluent. This gave 3.29 g (84%) of the title compound as a colorless oil. HRMS m/z calcd for C12H11ClN2O (M)+ 234.0560, found 234.0551.
