Reaktionsschritte
A solution of 3,5-dichloropyrazine-2-carbonitrile (86 mg, 0.494 mmol), D-phenylalaninamide (81 mg, 0.494 mmol) and DIEA (0.130 mL, 0.747 mmol) in DMF (2 mL) was stirred at room temperature for 20 h. Water and EtOAc were added. Organic phase was separated, washed with 1N HCl, then with 5% NaHCO3, dried over Na2SO4, concentrated in vacuo to give (R)-2-(6-chloro-5-cyanopyrazin-2-ylamino)-3-phenylpropanamide (128 mg) as an oil.
