Procedure

2-Hydroxy-2-(4-(5-(3-phenyl-4-(trifluoromethyl)isoxazol-5-yl)-1,2,4-oxadiazol-3-yl)phenyl)acetic acid (Int-Va, 30 mg, 0.070 mmol),2-(methylsulfonyl)ethanamine (12.85 mg, 0.104 mmol), HATU (34.4 mg, 0.090 mmol), and 4-methylmorpholine (28.1 mg, 0.278 mmol) were added to DMF (1 mL). This was stirred for 1 h before it was purified by prep HPLC (PHENOMENEX® Luna 5u 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=11.5 min) to provide 2-hydroxy-N-(2-(methylsulfonyl)ethyl)-2-(4-(5-(3-phenyl-4-(trifluoromethyl)isoxazol-5-yl)-1,2,4-oxadiazol-3-yl)phenyl)acetamide (15 mg, 0.027 mmol, 38.2% yield) as a single enantiomer. LCMS=537.3 [M+H]+; 1H NMR (400 MHz, methanol-d4) δ ppm 8.17 (2 H, d, J=8.58 Hz), 7.54-7.74 (7 H, m), 5.14 (1 H, s), 3.73 (2 H, t, J=6.60 Hz), 3.35 (2 H, t, J=6.60 Hz), 2.97 (3 H, s); HPLC peak RT=9.3 min (Method A).
