Procedure

TFA (1.5 ml) was added to a stirred solution of 1-(4-Methoxycarbonyl-benzyl)-5-propylsulfanyl-1H-pyrazole-4-carboxylic acid tert-butyl ester (Intermediate#46) (274 mg, 0.70 mmol) in DCM (6 ml). The reaction was stirred at ambient temperature for 3 hours then evaporated in vacuo. The resulting gum was sonicated with isohexane to yield a solid. The solvent was removed then the white solid was dissolved in EtOAc and evaporated in vacuo to yield the title compound as an off white solid (236 mg, 100%).
