Participants

Reaction Steps

To a solution of acetic acid (30 mg, 0.5 mmol) and HATU (189 mg, 0.5 mmol) in DMF (2 mL) is added triethylamine (0.07 mL, 0.5 mmol). The reaction mixture is stirred at room temperature for 10 minutes and 2-[5-(2-amino-pyrimidin-5-yl)-1-tert-butyl-1H-benzimidazol-2-yl]-N-hydroxy-benzamidine (200 mg, 0.5 mmol) is added. The reaction mixture is stirred at room temperature for 0.5 hours then warmed to 80° C. and stirred for 15 hours. The reaction mixture is cooled to room temperature and concentrated in vacuo. EtOAc (20 mL) is added and the organics washed with H2O (30 mL) then dried (Na2SO4), filtered and concentrated. Purification via prep HPLC (0.1% TFA/MeCN) affords the title compound (27 mg, 8%) as 2TFA salt. LCMS (ESMS): m/z 426.20 (M++1)
