Participants

Reaction Steps

To a solution of 2-{(E)-2-[5-(4-fluoro-phenyl)-3-methyl-3H-[1,2,3]triazol-4-yl]-vinyl}-4-methyl-thiazole-5-carboxylic acid (75 mg, 0.22 mmol) and TBTU (77 mg, 0.24 mmol) in DMF (0.4 mL) was added DIPEA (186 μL, 1.09 mmol). Then isopropylamine (21 μL, 0.24 mmol) was added and the mixture was stirred at room temperature under Ar for 1 h. The mixture was then evaporated and purification by chromatography (silica, 1 to 5% methanol in dichloromethane) afforded the title compound (28 mg, 33%) as an off white solid after recrystallisation from ethylacetate and heptane. MS: m/e=386.4 [M+H]+.
