Reaction Steps

A mixture of 3-[({1-[(3,4-dichlorophenyl)methyl]-5-methyl-1H-1,2,3-triazol-4-yl}carbonyl)amino]benzoic acid (Example 63) (0.143 g, 0.35 mmol), ethylamine in THF, 2M solution (1.75 mL, 0.35 mmol), HATU (0.199 g, 0.52 mmol) and DIPEA (0.09 mL, 0.52 mmol) in DMF was stirred at 40° C. for 1 week. The solvent was evaporated and the residue was washed with water and extracted with DCM. The organic phase was dried over sodium sulphate, filtered and concentrated. The title compound was obtained after recrystallisation from acetonitrile as white solid (49 mg, 32%). HRMS calculated for C20H19Cl2N5O2 (M+H)+ 432.0994. found: 432.0957, Rt: 2.82 min. MP: 192.2° C.
