Reaction Steps

5-(N-Hydroxycarbamimidoyl)-6-methyl-2-oxo-1-(3-trifluoromethyl-phenyl)-1,2-dihydro-pyridine-3-carboxylic acid 4-methanesulfonyl-benzylamide (0.011 g, 0.021 mmol), acetic anhydride (0.02 g, 0.195 mmol), toluene (2 ml) and a magnetic stirrer bar were placed in a vial. The vial was sealed and was heated (110° C.) with stirring for 5 h. LC-MS confirmed the consumption of the starting material and the formation of a product with the expected MW. Evaporation and purification on preparative HPLC gave the title compound (0.004 g, 35%) as a white solid after freeze-drying the pure fractions.
