Reaction Steps

To a solution of 2,6-dichloropyrazine (298 mg, 2.00 mmol) and 1-(3-fluorophenyl)ethanol (308 mg, 2.2 mmol) in dioxane (5 mL) was added NaH (55% in oil, 96 mg, 2.2 mmol) at room temperature. The reaction mixture was stirred over night. Water (0.5 mL) was added and the mixture was stirred for 15 min. Drying (K2CO3), filtration, and concentration in vacuo gave the title compound as an oil (0.55 g) that was used directly in the next step. MS m/z 254 (M+H)+.
