실험 절차

A solution of 2-bromoisonicotinic acid (160 mg, 0.792 mmol), HATU (331 mg, 0.871 mmol) and DIPEA (0.655 mL, 3.96 mmol) in DMF (8 mL) was stirred at rt for 10 min. N-(5-amino-2-methylphenyl)thieno[2,3-b]pyrazine-6-carboxamide hydrochloride 29 (248 mg, 0.871 mmol) was added and stirred at rt for 3 h. Quenched in 3% citric acid solution and the resulting precipitate was collected. Triturating with acetonitrile gave N-(5-(2-bromoisonicotinamido)-2-methylphenyl)thieno[2,3-b]pyrazine-6-carboxamide (30) (163 mg, 44%). (m/z)=468 and 470 (M+H)+.
