(R)-4-(1-(1-aminopropan-2-yl)-1H-pyrazol-3-yl)-2-chloro-3-methylbenzonitrile (300 mg, 1.09 mmol) was coupled with 3-acetyl-1H-pyrazole-5-carboxylic acid (202 mg, 1.31 mmol) using the method of Example 34(d). Crude product was purified by CombiFlash (column: C-18, eluent: 0-100% MeCN in water) to yield 83 mg (19%) of the title compound. 1H-NMR (400 MHz; CDCl3): δ 1.62 (d, 3H), 2.52-2.58 (m, 6H), 3.79 (dd, 1H), 3.91 (dd, 1H), 4.60-4.71 (m, 1H), 6.92 (d, 1H), 7.25 (s, 1H), 7.27-7.29 (m, 1H), 7.52 (d, 1H), 7.54-7.60 (m, 2H).
