5-Fluoro-2-(methylthio)benzo[d]thiazole-6-carbonitrile was synthesized as an orange solid (1.2 g, 86%) using a procedure analogous to that described in Step 2 of Example 114, substituting 6-cyano-5-fluorobenzo[d]thiazole-2-thiolate potassium salt from the previous step for ethyl 2-mercaptothiazolo[4,5-b]pyridine-6-carboxylate potassium salt used in Example 114. 1H NMR (300 MHz, DMSO-d6) δ 8.67 (d, J=6.4 Hz, 1H), 8.01 (d, J=10.5 Hz, 1H), 2.84 (s, 3H); LCMS (ESI) m/z 225 (M+H)+.
