实验步骤: 5-Chloro-1-(5-methanesulfonyl-pyridin-2-yl)-3-trifluoromethyl-1H-pyrazole-4-carbonitrile (0.35 g, 1 mmol) and (4-methylene-cyclohexyl)-methanol (0.252 g, 2 mmol) were dissolved in dry dimethylsulfoxide (DMSO) (5 ml) and potassium fluoride (0.116 g, 2 mmol) was added to the clear solution. The resulting mixture was stirred at 20° for a period of 48 hours. Analytical HPLC indicated the reaction completion. The reaction mixture was poured into water (50 ml) and the resulting mixture was extracted with ethyl acetate (20 ml). The organic extract was dried over magnesium sulfate and concentrated with a rotary evaporator. The desired product (0.3 g, 68%) was isolated by chromatography on silica gel eluting with a solution of 15% of ethyl acetate and 15% of acetone in hexane. MS: 440, r.t.: 3.0. the resulting mixture was extracted with ethyl acetate (20 ml) The organic extract was dried over magnesium sulfate concentrated with a rotary evaporator

实验步骤: To a solution of ethyl 4-methylenecyclohexanecarboxylate (2 g, 11.89 mmol) in ether (40 mL) was added LAH (0.5 g, 13.17 mmol) portionwise under N2. The reaction mixture was refluxed for 1 h and was quenched by addition of 1 mL of EtOAc carefully and refluxed for 10 min. The reaction mixture was cooled down and added 3 mL of 1 N NaOH and stirred for 5 min, filtered off the solid and washed with ether. The filtration was washed with water, brine, dried (MgSO4), and removed the solvent to afford (4-methylenecyclohexyl)methanol.
