To a stirred solution of N3-(3,5-dichlorophenyl)-1H-1,2,4-triazole-3,5-diamine Intermediate 2 (80 mg, 0.33 mmol) in 5 mL methanol, was added 3-(trifluoromethyl)benzaldehyde (114 mg, 0.66 mmol). The reaction mixture was stirred overnight, after which, sodium borohydride (24.8 mg, 0.656 mmol) was added and the mixture was for stirred for 10 min. The reaction was diluted the water (20 mL) and extracted with EtOAc (3×10 mL). The organic layers were combined and dried with sodium sulfate. The solvent was removed and the residue was chromatographed on a combiflash machine (6% methanol/methylene chloride) to give 61 mg (46%) of the desired product. MS +m/z: 401.9 (M+H)+
