Versuchsvorschrift

A mixture of 1-[(3,4-dichlorophenyl)methyl]-5-methyl-1H-1,2,3-triazole-4-carboxylic acid (Intermediate 11) (0.4 g, 1.3 mmol), dimethyl 5-amino-1,3-benzenedicarboxylate (0.29 g, 1 eq), HATU (0.69 g, 1.3 eq) and DIPEA (0.34 mL, 1.3 eq) in DMF (10 mL) was stirred at 45° C. for 24 hours. The solvent was evaporated and the residue was washed with water and extracted with DCM. The organic phase was dried over sodium sulphate and concentrated. The title compound was obtained as a white solid (650 mg, 95%) after recrystallisation from acetonitrile. LC/MS: m/z 477 (M+H)+, Rt: 3.81 min.
