Diphenylacetic Acid → N-[5-(2-Chloro-benzyl)-thiazol-2-yl]-2,2-diphenyl-acetamide

Participants

Reaction Steps

5-(2-Chloro-benzyl)-thiazol-2-ylamine (45 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 (10.3 mg, 0.0246 mmol, 12%). ESI-MS m/z calc. 418.1. found 419.2 (M+1)+ Retention time 3.85 minutes. 1H NMR (400 MHz, DMSO-d6) δ 4.19 (s, 2H), 5.30 (s, 1H), 7.23-7.47 (m, 15H).
