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, 20 mg, 0.046 mmol), 5-(aminomethyl)tetrazole (6.89 mg, 0.070 mmol), 4-methylmorpholine (18.76 mg, 0.185 mmol), and HATU (22.92 mg, 0.060 mmol) were added to DMF (1 mL). This was stirred for 1 h and was 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=29.2 min) to provide (R/S)-N-((1H-tetrazol-5-yl)methyl)-2-hydroxy-2-(4-(5-(3-phenyl-4-(trifluoromethyl)isoxazol-5-yl)-1,2,4-oxadiazol-3-yl)phenyl)acetamide (12 mg, 0.023 mmol, 49.8% yield): LCMS=513.2 [M+H]+; 1H NMR (400 MHz, methanol-d4) δ ppm 8.11-8.24 (2 H, m), 7.53-7.75 (7 H, m), 5.22 (1 H, s), 4.67-4.81 (2 H, m); HPLC peak RT=8.8 min (Method A).
