Reaction Steps

To a solution of 2,6-dichloropyrazine (444 mg, 3.00 mmol) and 3-methoxybenzyl alcohol (455 mg, 3.30 mmol) in dioxane (5 mL) was added NaH (55% in oil, 144 mg, 3.30 mmol) at room temperature. The reaction mixture was stirred overnight. Water (0.5 mL) and ethyl acetate (10 mL) were added and the mixture was stirred for 15 min and then filtered. The filtrate was dried over K2CO3 and concentrated to give an oil (0.86 g) that was used directly in the next step. MS m/z 250 (M+H)+.
