実験手順
A mixture of 2-((2S)-bicyclo[2.2.1]heptan-2-ylamino)-5-methyl-5-(piperidin-4-ylmethyl)thiazol-4(5H)-one (534 mg, 1.66 mmol), 4-[2-(Boc-amino)ethyloxy]-benzoic acid (NeoMPS, 701 mg, 2.49 mmol), EDCI (Aldrich, 637 mg, 3.32 mmol, 2.0 eq), HOBt (Aldrich, 45 mg, 0.332 mmol, 0.2 eq) and triethylamine (Aldrich, 336 mg, 3.32 mmol, 2.0 eq) in CH2Cl2 (10 mL) was stirred at room temperature for ca. 18 h. The reaction was quenched with saturated NaHCO3 (100 mL), and the crude product was extracted with CH2Cl2 (3×100 mL). The combined organic extracts were washed with brine, dried over Na2SO4, filtered, and concentrated. Flash column chromatography (silica gel, 0-5% MeOH in CH2Cl2) afforded the title compound as a white solid (800 mg). MS (ESI, pos. ion) m/z: 585 (M+H).
