The synthetic route is as follows., COA of Formula: C4H5ClN2

(b) S-Chloropyrazole-S-carboxylic acidA mixture of 5-chloro-3-methylpyrazole (3.6 mmol; see step (a) above), water (6 mL) and fert-butanol (1.2 mL) was heated to 750C, after which KMnO4 (1.42 g, 9 mmol) was added. The mixture was stirred at 75 C overnight and filtered hot. The solids were washed with boiling water. The combined cooled filtrates were extracted with EtOAc, and the combined extracts washed with NaCl (sat., aq.), dried (MgSO4) and concentrated. The crude solid was recrystallised from EPO EtOAc/hexane/pentane to give the sub-title compound as white crystals (Yield:350 mg (67%)).1H-NMR (DMSO-d6, 400 MHz), delta 13.65 (br s, IH), 6.80 (s, IH)
