The result was acetylsalicylic acid, the modern active ingredient in aspirin.

结果是酰水杨酸，阿司匹林的现代活性分。

So, the active ingredient in aspirin is a compound called acetylsalicylic acid.

阿司匹林的活性分是一种酰水杨酸的化合物。

Soon, aspirin became synonymous with acetylsalicylic acid.

很快，阿司匹林酰水杨酸的代名词。

In 1853, a French chemist managed to chemically synthesize the compound, creating a substance called acetylsalicylic acid.

1853 年， 一位法国化学家功地化学合这种化合物，产生一种酰水杨酸的物质。

Now if you swap the methyls out for a couple of other slightly more complicated groups, then you get acetylsalicylic acid, or aspirin.

现在， 如果将甲基换其他几个稍微复杂一些的基团，会得到酰水杨酸或阿司匹林。

And thus, we can build the compounds we need, whether it be the simple stuff, like acetylsalicylic acid, aspirin, or something more complicated, like alpha-(5,6-dimethylbenzimidazolyl)cobamidcyanide, better known as vitamin B12.

因此，我们可以构建我们需要的化合物， 无论是简单的东西， 如酰水杨酸、阿司匹林，还是更复杂的东西， 如 α-(5, 6-二甲基苯并咪唑基)cobamidcyanide， 也是众所周知的维生素 B12。
