Participants

Reaction Steps

To a solution of 4-methyl-2-[(E)-2-(3-methyl-5-pyridin-2-yl-3H-[1,2,3]triazol-4-yl)-vinyl]-thiazole-5-carboxylic acid (56 mg, 0.17 mmol) and TBTU (60 mg, 0.19 mmol) in DMF (0.9 mL) was added DIPEA (146 μL, 0.86 mmol). Then isopropylamine (16 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 10% methanol in dichloromethane) afforded the title compound (36 mg, 57%) as a light yellow solid after recrystallisation from methanol-water. MS: m/e=369.2 [M+H]+.
