Versuchsvorschrift

A solution of 3,5-dichloropyrazine-2-carbonitrile (348 mg, 2.00 mmol), D-leucinamide hydrochloride (333 mg, 2.00 mmol) and DIEA (1.00 mL, 5.75 mmol) in NMP (8 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)-4-methylpentanamide as an oil (535 mg).
