To a stirred solution of 5-(4-isopropoxycyclohex-1-en-1-yl)-4-methylisoxazole-3-carboxylic acid (174 mg, 0.656 mmol) in dry NMP (3 mL), HATU (274 mg, 0.721 mmol) was added followed by 4-amino-2-cyclohexyl-1,5-dimethyl-1H-pyrazol-3(2H)-one (Intermediate D) (151 mg, 0.721 mmol) and triethylamine (0.201 mL, 1.443 mmol). The mixture was stirred at room temperature overnight. The resulting mixture was partitioned between EtOAc (20 mL) and 1M NaOH (aq) (20 mL) and the organic phase was washed with water (30 mL), brine (30 mL), dried over MgSO4, filtered and concentrated under reduced pressure. The crude material was dissolved in DMSO and purified using a UV-directed reverse phase chromatography with a gradient of 40-80% MeCN in water (0.1% formic acid) over 9.5 minutes. The product fraction was added to EtOAc (50 mL) and washed with a saturated aqueous NaHCO3 solution (50 mL). The organic phase was dried over MgSO4, filtered and concentrated under reduced pressure to afford the title compound;
