Procedure

This compound was prepared in a manner similar to that shown in Scheme 3, using 5-bromo-6-fluoro-1H-indazole (88d), which was treated with t-butyl lithium and carbon dioxide to yield 6-fluoro-1H-indazole-5-carboxylic acid. This compound in turn was treateded with thiosemicarbazide and polyphosphoric acid to form 5-(6-fluoro-1H-indazol-5-yl)-1,3,4-thiadiazol-2-amine. MS (API-ES) m/z (%): 236 (100%, M++1).
