실험 절차

(S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (219 mg, 0.84 mmol) was coupled with 3-methyl-1,2,4-oxadiazole-5-carboxylic acid using the method of Example 34(d). Crude product was suspended in MeCN and MeOH. Suspension was filtered to give 16 mg (5%) the title compound as a colourless solid. Filtrate was purified by CombiFlash (column: C-18 silica, eluent: 0-100% MeCN in water). Fractions containing the title compound were combined and suspended in MeCN. Suspension was filtered to give 9 mg (3%) the title compound. 1H-NMR (400 MHz; d6-DMSO): δ 1.19 (d, 3H), 2.44 (s, 3H), 4.34 (d, 2H), 4.39-4.53 (m, 1H), 6.95 (d, 1H), 7.84 (d, 1H), 7.92 (dd, 1H), 7.98 (d, 1H), 8.06 (d, 1H), 9.42 (d, 1H).
