反応手順

A mixture of 1-[(3,4-dichlorophenyl)methyl]-5-methyl-1H-1,2,3-triazole-4-carboxylic acid (Intermediate 4) (0.1 g, 0.35 mmol), 2-amino-6-methoxybenzothiazole (0.062 g, 0.35 mmol), HATU (0.082 g, 0.45 mmol) and DIPEA (85 μL, 0.45 mmol) in DMF (5 mL) was stirred at 45° C. for 3 days. 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 in vacuo. The residue was purified by flash chromatography eluting with DCM/MeOH (99/1) to give after trituration in diisopropyl ether, the title compound as a white solid (15 mg, 10%). HRMS calculated for C19H15Cl2N5O2S (M+H)+ 448.0402, found: 448.0403, Rt: 3.31 min. MP: 225° C.
