2-(4-amino-phenyl)-3-cyclopentyl-N-thiazol-2-yl-propionamide 、
三氟甲烷磺酰氯 在
ethyl acetate heptane 作用下,
以
吡啶 为溶剂,
反应 7.0h,
以High pressure liquid chromatography (Chromegasphere SI-60, 10 μM, 60 Å, 25 cm×23 cm ID, 40/60 heptane/ethyl acetate) afforded the 3-cyclopentyl-N-thiazol-2-yl-2-(4-trifluoromethanesulfonylamino-phenyl)-propionamide (93.8 mg, 41.9%) as a tan solid的产率得到3-cyclopentyl-N-thiazol-2-yl-2-(4-trifluoromethanesulfonylamino-phenyl)-propionamide
