실험 절차

(R/S)-2-Hydroxy-2-(4-(5-(3-phenyl-4-(trifluoromethyl)isoxazol-5-yl)-1,2,4-oxadiazol-3-yl)phenyl)acetic acid (Int-V, 25 mg, 0.058 mmol) was dissolved in DMF (1 mL) and 4-methylmorpholine (0.038 mL, 0.348 mmol), 2-amino-N-methylacetamide, HCl (14.44 mg, 0.116 mmol), and HATU (39.7 mg, 0.104 mmol) were added. This solution was stirred overnight and was then purified by preparative HPLC (PHENOMENEX® Luna 5u C18 21.2×100 mm, gradient elution with Method 1—MeOH/water containing 0.1% trifluoroacetic acid as defined above, 0% B to 100% B over 10 min, 20 mL/min, 220 nM, product retention=11.4 min) to give (R/S)-2-hydroxy-N-(2-(methylamino)-2-oxoethyl)-2-(4-(5-(3-phenyl-4-(trifluoromethyl)isoxazol-5-yl)-1,2,4-oxadiazol-3-yl)phenyl)acetamide (6.2 mg, 0.012 mmol, 19.97% yield): LCMS=502.2 [M+H]+; 1H NMR (400 MHz, methanol-d4) δ ppm 8.14-8.23 (2 H, m), 7.66-7.79 (4 H, m), 7.52-7.66 (3 H, m), 5.20 (1 H, s), 3.88-4.00 (2 H, m), 3.78-3.88 (2 H, m), 2.75 (3 H, s); HPLC Peak RT=8.1 min (Analytical Method C).
