Procedure

To a solution of 3-[1-(4-methoxy-phenyl)-5-p-tolyl-1H-pyrazol-3-yl]-2-m-tolyl-propionic acid (product of Method 2) (100 mg, 0.23 mmol), EDC (65 mg, 0.35 mmol), and HOBT (46 mg, 0.34 mmol) in DMF (4.0 mL) was added trans-2-aminocyclohexanol hydrochloride (52 mg, 0.34 mmol) and DIEA (0.20 mL, 1.2 mmol). The reaction mixture was stirred for 24 h, diluted with EtOAc, and washed with 1.0 N NaOH (2×25 mL), water (1×25 mL), 5% formic acid (2×25 mL), water (1×25 mL) and brine (1×25 mL). The organic layer was dried (Na2SO4) and the solvent was removed under reduced pressure. Reversed-phase HPLC afforded 40 mg (33%) of N-(2-hydroxy-cyclohexyl)-3-[1-(4-methoxy-phenyl)-5-p-tolyl-1H-pyrazol-3-yl]-2-m-tolyl-propionamide as a mixture of diastereomers. HPLC: Rt=3.17 (Method B). MS (ES+): mass calculated for C33H37N3O3, 523.28; m/z found 524.2 [M+H]+. 1H NMR (400 MHz, CDCl3): 7.92-7.85 (m, 1H), 7.26-7.10 (m, 6H), 7.05-7.01 (m, 3H), 6.94-6.91 (m, 2H), 6.32 (s, 0.5H), 6.29 (s, 0.5H), 4.42 (d, J=4.7 Hz, 0.5H), 4.34 (d, J=5.4 Hz, 0.5H), 3.90 (ddd, J=5.4, 9.4, 20.3 Hz, 1H), 3.76 (s, 3H), 3.24 (m, 0.5H), 3.17 (m, 0.5H), 2.85 (m, 1H), 2.30 (s, 1.5H), 2.28 (s, 1.5H), 2.27 (s, 3H), 1.75 (m, 1H), 1.55 (m, 2H), 1.13 (m, 4H), 0.97 (m, 1H).
