Procedure

A solution of 3,5-dichloropyrazine-2-carbonitrile (150 mg, 0.862 mmol), D-alaninamide hydrochloride (107 mg, 0.858 mmol) and DIEA (0.400 mL, 2.30 mmol) in NMP (4 mL) was stirred at room temperature for 20 h. Water and EtOAc were added. Organic phase was separated, dried over Na2SO4, concentrated in vacuo to give (R)-2-(6-chloro-5-cyanopyrazin-2-ylamino)propanamide as an oil (194 mg).
