To a solution of 5-(5-methyl-1-(3-(piperazin-1-yl)benzyl)-1H-1,2,4-triazol-3-yl)-3-(4-(trifluoromethoxy)phenyl)-1,2,4-oxadiazole (Example 81; 110 mg, 0.23 mmol), 2-hydroxyacetic acid (21 mg, 0.28 mmol) and DIPEA (89 mg, 0.69 mmol) in DMF (5 mL) was added HATU (106 mg, 0.28 mmol). The resulting mixture was stirred at room temperature for 3 h, diluted with H2O (10 mL) and extracted with EtOAc (2×10 mL). The combined organic layers were washed with H2O (10 mL) and brine (10 mL), dried over Na2SO4, filtered and concentrated under reduced pressure; the residue was purified by prep-HPLC (20% to 50% MeCN/H2O containing 0.1% trifluoroacetic acid) to give the title compound as a white solid; MS (ES+) C25H24F3N7O4 requires: 543. found: 544 [M+H]+; 1H-NMR (500 MHz, DMSO-d6) δ 8.23 (d, J=8.5 Hz, 2H), 7.62 (d, J=8.5 Hz, 2H), 7.24 (m, 1H), 6.95 (m, 2H), 6.69 (d, J=7.5 Hz, 1H), 5.49 (s, 2H), 4.12 (s, 2H), 3.56 (m, 2H), 3.15 (m, 4H), 2.58 (s, 3H), 2.50 (m, 2H).
