Procedure

To a stirred solution of trans-[4-(3,4,5-trimethyl-pyrazol-1-ylmethyl)-cyclohexyl]-carbamic acid tert-butyl ester (step 2)(215 mg, 0.669 mmol) in methanol (3 mL) at room temp is added a solution of 4M HCl in dioxane (3 mL). The mixture is stirred at room temp for 1 hour and then concentrated in vacuo. The resulting gum is dried under vacuum overnight to afford the title compound which is used without further purification. 1H NMR (400 MHz, CDCl3) δ 8.16 (3H, br s), 4.10 (2H, d), 2.90 (1H, m), 2.29 (3H, s), 2.27 (3H, s), 2.01-1.90 (5H, m including 3H, s), 1.83 (1H, s), 1.54 (2H, m), 1.30 (2H, m), 1.12 (2H, m). (NMR shows contamination with side products and solvents.)
