Procedure
Trifluoroacetic acid (4.72 mL, 61.46 mmol) was added to tert-butyl 5-(cyclohexylthio)-1-(4-(methoxycarbonyl)phenyl)-1H-pyrazole-4-carboxylate (Intermediate#89) (2.56 g, 6.15 mmol) in CH2Cl2 (40 mL) The resulting solution was stirred at 20° C. for 24 hours. The reaction mixture was evaporated to dryness, re-dissolved in dioxan (20 mL) and re-evaporated to dryness to afford 5-(cyclohexylthio)-1-(4-(methoxycarbonyl)phenyl)-1H-pyrazole-4-carboxylic acid (2.25 g, 100%) as a white crystalline solid.
