Acetyl chloride → HCID 59694012, compound

Participants

Reaction Steps

To a solution of 5-methylpyrazin-2-amine (300 mg, 2.75 mmol) in dried THF (9 mL) were added acetyl chloride (0.21 mL, 2.89 mmol) and TEA (0.75 mL, 5.50 mmol). The reaction mixture was stirred for 3 hours after which, it was partitioned between ethyl acetate and water. The organic layer was separated and the aqueous layer was extracted with ethyl acetate. The combined organic extracts were washed with brine, dried over MgSO4, celite filtered and concentrated under reduced pressure. The crude product was purified by flash chromatography using (10% to 30% Ethyl acetate/Hexane) as a solvent to afford title compound (360 mg, 86% yield). MS m/z: 152 [M+1].
