Reaction Steps
To a solution of Example 63C (0.73 g, 3.1 mmol) in tetrahydrofuran (20 mL) were added 2-methoxy-5-(trifluoromethyl)benzoic acid (0.68 g, 3.1 mmol, JRD Fluorochemicals), 1-hydroxybenzotriazole (0.47 g, 3.1 mmol, Aldrich), N-(3-dimethylaminopropyl)-N-ethylcarbodimide hydrochloride (0.59 g, 3.1 mmol) and triethylamine (1.3 mL, 9.2 mmol). After stirring at 60° C. for 16 hours, the reaction mixture was cooled and quenched with saturated NaHCO3 (20 mL). The aqueous layer was extracted with ethyl acetate (3×20 mL). The combined organic extracts were dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure. The residue was purified by column chromatography using an Analogix® Intelliflash280™ (SiO2, 0-50% ethyl acetate in hexanes) to provide 0.2 g of the title compound. MS (ESI+) m/z 440 (M+H)+.
