実験手順
(R)-2-acetyl-N-(1-(3-(3-chloro-4-cyano-2-methylphenyl)-1H-pyrazol-1-yl)-butan-2-yl)thiazole-4-carboxamide was prepared using the method of Example 34(d) starting from (R)-4-(1-(2-aminobutyl)-1H-pyrazol-3-yl)-2-chloro-3-methylbenzonitrile (489 mg, 1.355 mmol) and 2-acetylthiazole-4-carboxylic acid (278 mg, 1.626 mmol). The product was purified by Flash-chromatography. Yield 11.4%. 1H-NMR (400 MHz; CDCl3): δ 1.05 (t, 3H), 1.56-1.67 (m, 2H), 2.53 (s, 3H), 2.53 (s, 3H), 4.36-4.52 (m, 3H), 6.42 (d, 1H), 7.47-7.55 (m, 3H), 7.88 (d, 1H), 8.39 (s, 1H).
