Procedure

1-(4-methoxycarbonylphenyl)-5-propylsulfanyl-pyrazole-4-carboxylic acid (Intermediate #7) (160 mg, 0.5 mmol), 2-adamantylamine hydrochloride (94 mg, 0.5 mmol), HOBT (81 mg, 0.6 mmol) and DIPEA (261 μL, 1.5 mmol) were dissolved in DMF (5 mL) and treated at ambient temperature with EDCI (115 mg, 0.6 mmol). The mixture was stirred at ambient for 18 h and then diluted with ethyl acetate (50 mL), washed with water (3×20 mL) and brine, dried (MgSO4) and evaporated to leave a white solid, which was purified by chromatography on silica gel, (12 g silica 0-50% EtOAc/isohexane) to give the title compound as a white solid. (203 mg, 92%)
