What is this molecular diagram?

This graffiti diagram was found in the public bathroom at my office building. I'm curious what it is, any ideas?

Best answer: methylphenidate which is also known as ritalin.

Not sure exactly. Reminds of ritalin or other similar drugs. It's been a while since I did any chemistry.

I was going to guess a mind drug. Quick work there, sg.

Also that graffiti spells lobotomy quite wrong.

For future reference, if you're looking to ID a molecular structure, ChemExper's advanced search will let you draw in a structure and give you a name for the chemical.

(also the handy chemist next to me in bed was useful)

Response by poster: I ran a bunch of typical drugs through google image search, but Ritalin didn't make the cut. Thanks.

I drew this, but didn't get any results, FWIW.

vidur, you've got three extra methyls on your terminal ester. It's a methyl, you've got it as a t-butyl. If you put in the structure given, you get methylphenidate, Ritalin, [113-45-1].

Thanks!

(Vidur, bonehead is pointing out that you don't draw hydrogen atoms attached to carbon atoms in organic chemistry diagrams. It's shorthand; it's just assumed that all the bonds you don't draw are hydrogen. So what you drew has a carbon at the bottom left with three more carbons branching off it, each of which would have their hydrogens. Also, your line off the nitrogen would suffer the same problem, implying a carbon at the end of that line.)

Thanks, introp. I got it when bonehead pointed it out. As a chemical engineer (though I haven't been employed as one for about 10 years now), I should have remembered this :)

ChemSpider is another free source that has structure search.
