Reaction Steps

(S)-3-acetyl-N-(1-(3-(3-chloro-4-cyano-2-methylphenyl)-1H-pyrazol-1-yl)-propan-2-yl)-1H-pyrazole-5-carboxamide (0.04 g, 0.097 mmol) as prepared in the previous Example was added in ethanol (5 ml). Solid sodium borohydride (0.018 g, 0.487 mmol) was added to the mixture and it was refluxed for 15 min under nitrogen. To the cooled solution a portion of 10 ml of saturated ammonium chloride was added and the mixture was extracted several times with DCM. The organic extracts were combined and washed with water, dried with Na2SO4, filtered and evaporated to dryness affording 0.040 g of the title compound. 1H-NMR (400 MHz; CDCl3): δ 1.25 (m, 3H), 1.51 (m, 3H), 2.49 (d, 3H), 3.72 (m, 1H), 4.29 (m, 1H), 4.41 (m, 1H), 4.61 (m, 1H), 4.99 (m, 1H), 6.42 (d, 1H), 6.56 (s, 1H), 7.43-7.50 (m, 3H), 7.53 (d, 1H).
