4,7-Difluoro-2-(methylthio)benzo[d]thiazole-6-carbonitrile was synthesized as a yellow solid (1.0 g, 37%) using a procedure analogous to that described in Step 2 of Example 114, substituting 6-cyano-4,7-difluorobenzo[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 (500 MHz, DMSO-d6) δ 8.04 (m, 1H), 2.88 (s, 3H); LCMS (ESI) m/z 243 (M+H)+.
