Reaction Steps
2-Amino-thiazole-4-carboxylic acid methyl ester (32 mg, 0.20 mmol) and diphenyl-acetic acid (42 mg, 0.20 mmol) were dissolved in N,N-dimethylformamide (1 mL) containing triethylamine (84.1 μL, 0.600 mmol). O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (84 mg, 0.22 mmol) was added and the solution was allowed to stir for 16 hours. The crude product was purified by reverse-phase preparative liquid chromatography (19 mg, 0.052 mmol, 26%). ESI-MS m/z calc. 366.1, found 367.1 (M+1)+ Retention time 3.34 minutes.
