Participants

Reaction Steps

(S)-2-acetyl-N-(2-(3-(3-chloro-4-cyanophenyl)-1H-pyrazol-1-yl)propyl)-oxazole-4-carboxamide was prepared using the method of Example 34(d) starting from (S)-4-(1-(1-aminopropan-2-yl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (521 mg, 2.00 mmol) and 2-acetyloxazole-4-carboxylic acid (372 mg, 2.40 mmol). The product was purified by Flash-chromatography. Yield 36.0%. 1H-NMR (400 MHz; CDCl3): δ 1.62 (d, 3H), 2.61 (s, 3H), 3.75-3.98 (m, 2H), 4.59-4.71 (m, 1H), 6.62 (d, 1H), 7.45-7.53 (m, 2H), 7.71 (d, 1H), 7.86 (dd, 1H), 7.98 (d, 1H), 8.32 (s, 1H).
