实验过程

(R)-3-[N-(5′-Chloro-2′-fluorobiphenyl-4-ylmethyl)-N′-(3-hydroxy-isoxazole-5-carbonyl)-hydrazino]-2-hydroxy-2-methyl-propionic acid ethyl ester (100 mg, 0.2 mmol) was dissolved in 1-heptanol (6 g, 50 mmol), followed by the addition of 4 M HCl in dioxane (1 mL, 4 mmol). The resulting mixture was stirred at room temperature for 8 hours, then evaporated under reduced pressure and purified (Interchim reverse phase chromatography column) The pure fractions were lyophilized to yield the title compound (27 mg, 95% purity). MS m/z [M+H]+ calc'd for C28H33ClFN3O6, 562.20; Found 562.2.
