实验步骤: 4-(4-Methylphenyl)butanol (0.5 g, 3.04 mmol) is dissolved in 5 ml DMF and to it is added imidazole (310 mg, 4.56 mmol) and tert-butyldimethylsilyl chloride (685 mg, 4.56 mmol). The reaction is stirred for 4 hrs after which it is extracted in ethyl acetate and washed with water to remove all DMF. The organic layer is then dried and concentrated. The crude mixture is then purified by flash chromatography using a mixture of ethyl acetate-hexanes as the eluting medium to afford the above mentioned product. is extracted in ethyl acetate washed with water to remove all DMF The organic layer is then dried concentrated The crude mixture is then purified by flash chromatography a mixture of ethyl acetate-hexanes as the eluting medium to afford the

实验步骤: To lithium aluminum hydride (427 mg, 11.2 mmol) suspended in dry ether (5 ml) at 0° C. is added 1 g of 4-(4-methylphenyl)butanoic acid (5.614 mmol) dissolved in dry ether (10 ml) over a period of 30 minutes. The reaction mixture is then allowed to warm to room temperature and stirred for 4 hours. Water (0.43 ml), NaOH (15% solution, 0.43 g) and water (1.29 ml) were then added successively and the resulting solution is stirred for 30 minutes. The resulting precipitate is filtered and washed with ether and dried. The filtrate is then concentrated and purified by flash chromatography using ethyl acetate-hexanes as the eluting medium. the resulting solution is stirred for 30 minutes The resulting precipitate is filtered washed with ether dried The filtrate is then concentrated purified by flash chromatography

实验步骤: To a suspension of 1.1 g of 60% sodium hydride in 30 ml of dimethyl sulfoxide under stirring at 70° C. for 30 minutes was added 4.1 g of 4-(4-methylphenyl)butanol at room temperature and stirred for 30 minutes. To a mixture was added 40 ml of tetrahydrofuran and was cooled at 0° C. To the resulting mixture was added dropwise a solution of 3.9 g of 6-chloromethyl-2-formylpyridine in 40 ml of tetrahydrofuran. After completion of the addition, the mixture was stirred at the same temperature for 30 minutes and further was stirred at room temperature for 4 hours. After completion of the reaction, the reaction mixture was poured into water, extracted with ethyl acetate and washed with water. The organic layer was dried over anhydrous magnesium sulfate and the solvent was distilled off under reduced pressure to give a residue as an oily substance. The residue was purified by column chromatography on silica gel by passing chloroform and methanol(100:1 ) to give 1.3 g of 6-[4-(4-methylphenyl) butoxy]methyl-2-formylpyridine. stirred for 30 minutes was cooled at 0° C After completion of the addition the mixture was stirred at the same temperature for 30 minutes further was stirred at room temperature for 4 hours After completion of the reaction extracted with ethyl acetate washed with water The organic layer was dried over anhydrous magnesium sulfate the solvent was distilled off under reduced pressure to give a residue as an oily substance The residue was purified by column chromatography on silica gel
