实验步骤: 8.0 g of 4-n-pentylcyclohexylmethanol was dissolved in a mixture solvent of 8 ml of pyridine and 8 ml of toluene. To the solution, 6.0 g of methanesulfonyl chloride was added dropwise below 10° C., followed by stirring overnight at room temperature. After the reaction, the reaction mixture was poured into cold water and subjected to extraction with toluene, followed by washing successively with 5%-hydrochloric acid aqueous solution and water and drying with anhydrous magnesium sulfate. The resultant organic layer was subjected to filtration, followed by distilling-off of the solvent to obtain 11.3 g of 4-n-pentylcyclohexylmethyl methanesulfonate. After the reaction subjected to extraction with toluene by washing successively with 5%-hydrochloric acid aqueous solution and water drying with anhydrous magnesium sulfate The resultant organic layer was subjected to filtration

After the reaction, the reaction mixture was acidified with 5%-hydrochloric acid aqueous solution until a pH value of 1 were shown and was subjected to extraction with ether. The organic layer was washed successively with water, 5%-sodium hydroxide, and water, followed by drying with anhydrous magnesium sulfate. The resultant organic layer was subjected to filtration, followed by distilling-off of the solvent to obtain 8.2 g of 4-n-pentylcyclohexylmethanol.

实验步骤: To a solution of 4-{2-[2-(4-benzyloxyphenyl)-5-methyl-1H-pyrrol-1-yl]ethyl}phenol (970 mg, 2.53 mmol), 4-pentylcyclohexylmethanol (699 mg, 3.79 mmol) and triphenylphosphine (994 mg, 3.79 mmol) in toluene (2 ml) was added 1,1′-(azodicarbonyl)dipiperidine (956 mg, 3.79 mmol) and the mixture was stirred at 80° C. for 12 hours. The reaction solution was poured into water and the mixture was extracted with ethyl acetate. The extract was dried over magnesium sulfate anhydride and the solvent was removed under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=30:1) to give the object compound as a solid. 1.11 g (yield: 79.9%) the mixture was extracted with ethyl acetate The extract was dried over magnesium sulfate anhydride the solvent was removed under reduced pressure The residue was purified by silica gel column chromatography (hexane:ethyl acetate=30:1)
