Reaction Steps

1H-Pyrazole-4-carbothioic acid amide (300 mg, 2.359 mmol) and 3-bromo-2-oxopropanoic acid (433 mg, 2.60 mmol) were dissolved in dry THF under nitrogen atmosphere. The reaction mixture was heated at 60° C. for 3 h. The reaction mixture was cooled to RT and evaporated to dryness. (R)-4-(1-(2-aminopropyl)-1H-pyrazol-3-yl)-2-chlorobenzonitrile (300 mg, 1.151 mmol) and DCM were added to the reaction flask and the title compound was prepared using the method of Example 34(d). The product was purified by Flash-chromatography and triturated using methanol. Yield 13.7%. 1H-NMR (400 MHz; DMSO): δ 1.17 (d, 3H), 4.31-4.54 (m, 3H), 6.96 (d, 1H), 7.84 (d, 1H), 7.87 (d, 1H), 7.94 (dd, 1H), 8.00 (bs, 1H), 8.06 (d, 1H), 8.08 (d, 1H), 8.38 (d, 1H), 8.40 (bs, 1H), 13.38 (s, 1H).
