Participants

Reaction Steps

To a solution of 3-((3-(4-chlorophenyl)-1,2,4-thiadiazol-5-yl)methoxy)-2,6-difluoro-N′-hydroxybenzimidamide (0.02 g, 0.05 mmol) in AcOH (0.50 ml) was added acetic anhydride (6 μL, 0.06 mmol) followed by addition of THF (1.0 ml) under nitrogen atmosphere. The resulting reaction mixture was stirred at room temperature for 1 h after which Pd-C (10%, 2.0 mg) was added and the resulting solution was stirred under hydrogen for 4 h. After the completion of the reaction (TLC monitoring), the reaction mass was filtered through celite bed, washed the celite bed with THF (3-4 times) and concentrated the filtrate. The residue was purified over neutral alumina (40% MeOH-DCM) to get the desired product (11 mg (58%).
