Procedure

(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, 30 mg, 0.070 mmol), 3-aminopropan-1-ol (7.84 mg, 0.104 mmol), 4-methylmorpholine (28.1 mg, 0.278 mmol), and HATU (34.4 mg, 0.090 mmol) were dissolved in DMF (1 mL). The mixture was stirred for 1 h and then purified by prep HPLC (PHENOMENEX® Luna 5u 21×250 mm, gradient elution with Method 1—MeOH/water containing 0.1% trifluoroacetic acid as defined above, 0% B to 100% B over 30 min, 25 mL/min, 220 nM, product retention=29.4 min) to provide (R/S)-2-hydroxy-N-(3-hydroxypropyl)-2-(4-(5-(3-phenyl-4-(trifluoromethyl)isoxazol-5-yl)-1,2,4-oxadiazol-3-yl)phenyl)acetamide (12 mg, 0.018 mmol, 26.5% yield): LCMS=489.1 [M+H]+; 1H NMR (400 MHz, chloroform-d) δ ppm 8.20 (2 H, d, J=8.35 Hz), 7.50-7.71 (7 H, m), 6.82-6.90 (1 H, m), 5.20 (1 H, s), 3.41-3.62 (4 H, m), 3.34 (3 H, s) HPLC peak RT=9.1 min (Method A).
