反応手順

To a solution of 2-amino-4-methyl-thiazole-5-carboxylic acid benzylamide (0.054 g, 0.22 mmol) and diisopropylethylamine (0.40 mL, 2.3 mmol) in dichloromethane (5 mL) was added 4-benzylbenzoic acid (0.057 g, 0.27 mmol), followed by the addition of N,N,N′,N′-tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (0.11 g, 0.28 mmol). The reaction was stirred at ambient temperature over 18 h then concentrated in vacuo. The crude product was purified by preparative HPLC (acetone/water gradient) to afford the title compound (0.003 g); MS (ES+) m/z 442 (M+1).
