Example 16; Synthesis of (S^-bis-trifluoromethyl-benzy^-t-Ccyclopentylmethyl-ethyl-amino)- ljS-dimethyl-lH-pyrazololS^-ZjJpyridine-S-ylmethyll-carbamic acid methyl ester; Step (i): Synthesis of N-(2,5-dimethyl-2H-pyrazol-3-yl)-acetamide; Pyridine (7,1 mL, 90 mmol) was added to a solution of 2,5-dimethyl-2H-pyrazol- 3-ylamine (10 g, 90 mmol) in acetic anhydride (46 mL) at 0 0C and the resulting mixture was stirred at room temperature for 30 min. The solvent was removed under vacuum to yield the title compound as a brownish liquid (13.7 g), yield: 100%. 1H ΝMR (400 MHz, CDC13): δ 7.91 (bs, IH), 5.98 (s, IH), 3.67-3.56 (m, 3H), 2.19-2.11 (m, 6H). ES-MS m/z 154 (M++ 1, 100%).
