3. Prior to use, the reagent was dried over anhydrous magnesium sulfate in dietileter.(在使用之前,试剂在无水硫酸镁中二甲醚干燥。)

4. The mixture was stirred for 2 hours at room temperature in dietileter.(混合物在室温下在二甲醚中搅拌2小时。)

5. The product was purified by column chromatography on silica gel eluting with a 5:95 mixture of dietileter and ethyl acetate.(产物通过硅胶柱层析纯化,洗脱溶剂为二甲醚和乙酸乙酯的5:95混合物。)

6. The reaction mixture was cooled to 0°C and a solution of 2,4-dinitrofluorobenzene in dietileter was added dropwise.(反应混合物冷却至0℃,然后滴加硝基氟苯二甲醚溶液。)

7. The oil was dissolved in dietileter and washed with water and brine several times.(将油在二甲醚中溶解,然后用水和盐水进行多次洗涤。)

8. The complex was extracted with warm dietileter and the solvent was removed under reduced pressure.(复合物用温二甲醚进行提取,然后在减压下去除溶剂。)

9. The compound was synthesized by reacting chloroacetyl chloride with 3-aminopropyltrimethoxysilane in dietileter.(该化合物通过氯乙酰氯和三甲氧基三甲基硅烷在二甲醚中反应合成。)
