Reaction Steps

A mixture of 2-[({1-[(3,4-dichlorophenyl)methyl]-1H-1,2,3-triazol-4-yl}carbonyl)amino]-1,3-thiazole-5-carboxylic acid (Intermediate 14) (0.18 g, 0.45 mmol), 2-aminoethanol (32 μL, 1.2 eq), HATU (0.22 g, 1.3 eq) and DIPEA (100 μL, 1.3 eq) in DMF (20 mL) was stirred at 40° C. for 48 hours. The solvent was evaporated and the residue was washed with water and extracted with DCM. The insoluble compound was filtered and washed with a mixture of acetonitrile/methanol 80/20 and then purified by flash chromatography eluting with DCM/MeOH (95/5) to give the title compound as a white solid (60 mg, 30%). HRMS calculated for C16H14Cl2N6O3S (M+H)+441.0303, found: 441.0339, Rt: 2.39 min. MP: 274.8° C.
