Reaction Steps

2-(4-Fluoro-phenyl)-N-hydroxy-1H-benzoimidazole-5-carboxamidine (501.9 mg, 1.86 mmol, example 3), triethylamine (645 μl, 4.63 mmol) and ethyl chloroformate (229 μl, 2.4 mmol) was dissolved in 35 ml of DMF. The mixture was heated to 80° C. for 7 hours. The mixture was evaporated. Ethyl acetate and water were added, the organic layer was separated, washed with water, dried and evaporated. The crude product was purified by preparative HPLC (RP18, acetonitrile/water 0.1% TFA) to yield 118 mg (21%) of the desired product. MS: m/e=297.05 (M+H+).
