Reaction Steps

The compound was synthesized as trifluoroacetate salt starting from 5-aminobenzimidazole (0.59 g, 4.4 mmol), cyclohexanecarbaldehyde (0.45 g, 0.485 mL, 4 mmol), TMSCN (0.5 mL, 4 mmol), PdC (10%, 0.05 g). di-(imidazol-1-yl)methanone (0.64 g, 3.92 mmol), as described in method 2. The product was purified via preparative HPLC using a water-acetonitrile gradient with 0.04% trifluoroacetic acid.
