実験手順

A solution of 3,5-dichloropyrazine-2-carbonitrile (158 mg, 0.908 mmol), (R)-2-amino-3-cyclopropylpropanamide hydrochloride (150 mg, 0.911 mmol) and DIEA (0.400 mL, 2.30 mmol) in NMP (5 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)-3-cyclopropylpropanamide (240 mg).
