4-AMINO-2-CHLORO-5-NITROBENZOTRIFLUORIDE

General procedure: Reaction mixture of K2CO3 (0.034 mol), compound 1 (0.028 mol), and compound 2 (0.014 mol) in DMSO (40 mL) was sonicated at 80 C for 5 min to yield compound 3d, for 100 min to yield 3a, for 120 min to yield 3c, and for 130 min to yield 3b. After cooling down the reaction mixture was poured into water, precipitate was filtered and dried.To a solution of Example 84 [5-CHLORO-6-TRIFLUOROMETHYL-2- [4- (3-TRIFLUOROMETHYL-PYRIDIN-2-YL)-PIPERAZIN-1-YL]-] 1H-benzoimidazole. (a) [5-CHLORO-4- (TRIFLUOROMETHYL)] benzene-1, 2-diamine. To a solution of 5-chloro-2-nitro-4- (trifluoromethyl) phenylamine (2 g, 8. 3 mmol, Oakwood) in EtOAc (26 mL) and [ETOH] (13 [ML) WAS] added tin [(II)] chloride dihydrate (13.1 g, 45 mmol, Aldrich). The reaction mixture was stirred at [70C] for 1 h. The light-yellow reaction solution was poured to crushed ice (50 mL) and carefully neutralized using saturated aqueous solution [OF NAHC03.] The resulting suspension was extracted with EtOAc (3 x 60 mL). The combined organic extracts were dried over [MGS04, ] filtered and the filtrate evaporatedcon in vacuo to give the title compound as white solid, which was used in the next step without additional purification. MS (ESI, pos. ion) [INLZ] : 211.4 (M+1).Starting material Iu:4-chloro-5-(trifluoromethyl)benzene-l, 2-diamine
