실험 절차

To a mixture of 3,5-dichloropyrazine-2-carbonitrile (500 mg, 2.84 mmol) and D-valinamide HCl salt (476 mg, 3.12 mmol) in AcCN (10 mL) was added DIPEA (1.11 mL, 6.25 mmol). After stirring at room temperature for 4 h, it was diluted with EtOAc, washed with sat. NaHCO3, organic layer was separated and washed with brine, dried and concentrated to give (R)-2-(6-chloro-5-cyanopyrazin-2-ylamino)-3-methylbutanamide (740 mg).
