Reaction Steps

A solution of 3,5-dichloropyrazine-2-carbonitrile (150 mg, 0.862 mmol), (R)-2-amino-2-phenylacetamide hydrochloride (160 mg, 0.858 mmol) and DIEA (0.400 mL, 2.30 mmol) in DMF (5 mL) was stirred at room temperature for 6 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)-2-phenylacetamide (245 mg).
