Ethanol → HCID 59336155, compound

Participants

Reaction Steps

To an ethanol solution (10 mL) of 2,3-dichloropyrazine (1.0 g), glycine ethyl ester hydrochloride (940 mg) and triethylamine (1.9 mL) were added and the mixture was irradiated with microwave (150° C., 10 min). The reaction mixture was concentrated under reduced pressure. To the resulting residue, a saturated aqueous sodium bicarbonate solution was added and the product was extracted with chloroform. The organic layer was dried over sodium sulfate and concentrated under reduced pressure. The resulting residue was purified by amino-coated silica gel (Fuji Sylysia Chemical Ltd.; NH-©M1020) column chromatography (hexane:ethyl acetate=10:1) to give 212 mg (15% yield) of the desired product.
