    • A method of producing (S)-3-[2-{(methylsulfonyl)oxy}ethoxy]-4-(triphenylmethoxy)-1-butanol methane sulfonate using 1,3-butadiene and a ketoethanal to form an intermediate racemic mixture. The racemic mixture is resolved to remove one isomer from the reaction product mixture. Following resolution, the following steps are performed: reduce the isomer to an alcohol, react the alcohol with triphenylmethyl chloride, ozonalyze the resulting reaction product, reduce the ozonalyzed product to yield a diol and react the diol with a methane sulfonyl compound to form (S)-3-[2-{(methylsulfonyl)oxy}ethoxy]-4-(triphenylmethoxy)-1-butanol methane sulfonate. Alternatively, the racemic mixture may first be reduced and the resulting racemic alcohol mixture is resolved to isolate one isomer of the alcohol and the remaining process steps are followed.
    • 使用1,3-丁二烯和酮代乙醇制备(S)-3- [2 - {(甲基磺酰基)氧基}乙氧基] -4-(三苯甲氧基)-1-丁醇甲磺酸盐以形成中间体外消旋混合物的方法。 拆分外消旋混合物以从反应产物混合物中除去一种异构体。 进行以下步骤:将异构体还原成醇,将其与三苯基甲基氯反应,对所得反应产物进行臭氧分解,减少臭氧分解产物,得到二醇并使二醇与甲磺酰化合物反应形成(S )-3- [2 - {(甲基磺酰基)氧基}乙氧基] -4-(三苯甲氧基)-1-丁醇甲磺酸盐。 或者,可以首先降低外消旋混合物,并将所得外消旋醇混合物溶解以分离醇的一种异构体,并遵循剩余的方法步骤。
