実験手順
To a solution of (S)-2-(3-(4-fluorobenzyl)-4-methyl-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid (0.11 g, 0.30 mmol) in anhydrous tetrahydrofuran (3.0 mL) was added 1-hydroxybenzotriazole (HOBt) (0.08 g, 0.60 mmol), 2-(1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate (TBTU) (0.19 g, 0.60 mmol), N,N-diisopropylethylamine (0.23 g, 1.80 mmol) and pyridin-3-ylmethanamine (0.05 g, 0.45 mmol). The resulting mixture was stirred at ambient temperature for 16 h and concentrated in vacuo. The residue was diluted in ethyl acetate (100 mL), washed with saturated aqueous sodium bicarbonate solution (20 mL), dried over anhydrous sodium sulphate and filtered. The filtrate was concentrated in vacuo and the residue was purified by column chromatography eluted with 2-8% methanol in dichloromethane to afford the title compound as a colorless solid (0.09 g, 70%): mp 67-70° C.
