To a solution of 4-(5-Amino-1H-[1,2,4]triazol-3-ylamino)-2,6-dichloro-benzonitrile (60 mg, 223 μmol) in MeOH (3.5 ml) was added 4-(trifluoromethyl)benzaldehyde (46.6 mg, 268 μmol, Aldrich) followed by acetic acid (36.7 mg, 35 μl, 611 μmol). The reaction was stirred at room temperature for 15 minutes, 2-picoline borane complex (32.2 mg, 349 μmol) was added and the stirring was continued for 4 days. The reaction mixture was poured into 0.1N HCl solution (20 ml) and extracted with EtOAc (3×20 ml). The combined organic solution was washed with brine, dried and concentrated in vacuo. Crystallization from DCM afforded a white solid as desired product (55 mg, 57% yield). MS +m/z: 427 (M+H)+
