Reaction Steps

Triethylamine (330.3 mg, 455.0 μL, 3.264 mmol) was added to a solution of tert-butyl N-(5-bromo-3-ethynyl-pyrazin-2-yl)-N-tert-butoxycarbonyl-carbamate (1000 mg, 2.511 mmol) and 4-(chloromethyl)-N-hydroxy-benzimidoyl chloride 6 (563.6 mg, 2.762 mmol) in DCM (7 mL). The mixture was stirred at RT overnight. The reaction mixture was partitioned between DCM and water and the organic extract was dried (MgSO4) and concentrated in vacuo yielding an oil that was dissolved in DCM (10 mL). TFA (2 mL) was added and the mixture was stirred at RT for 15 min before being concentrated in vacuo. MS (ES−) 364
