(S)—N-(1-(3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl)propan-2-yl)-5-methyl-1,3,4-oxadiazole-2-carboxamide was prepared using the method of Example 34(d) starting from (S)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (200 mg, 0.652 mmol) and 5-methyl-1,3,4-oxadiazole-2-carboxylic acid (100 mg, 0.782 mmol). The product was purified twice by Flash-chromatography (normal phase and reverse phase). Yield 3.7%. 1H-NMR (400 MHz; MeOD): δ 1.28 (d, 3H), 2.58 (s, 3H), 4.30-4.44 (m, 2H), 4.53-4.64 (m, 1H), 6.76-6.78 (m, 1H), 7.71 (d, 1H), 7.76-7.80 (m, 1H), 7.86-7.90 (m, 1H), 8.02-8.04 (m, 1H).
