 Okay, so let's do let's do this synthesis problem again. Let's do the synthesis problem again, okay? So in order to be able to do these synthesis problems, remember we're going to be drawing of like a roadmap, okay? So we can do it either forward or retro. Okay, either one works. You have to know what these compounds are how to draw them. Okay, so benzene of course Everybody's probably okay with drawing And Draw out aeronitro benzoic acid for me. So we're going to do that go from here to here So remember in order to do this we're not going to draw a mechanism. We're not going to Do anything like that. We're going to do a number of steps like a roadmap So I think somebody said if on did you we were the ones I said the first step, right? What was it? Yeah, so Okay, so we'll do a free-to-crash reaction, right and that gives us toluene Eventually this Methyl group will be turned into the benzoic acid and I think the last time we said well the first thing we want to do is do that what So somebody somebody mentioned right well we want to Oxidize this thing with potassium permanganate, right? But what did we say no that's a bad idea, right? But we want to do that as our last step, right? Why would that have been a bad idea to oxidize with potassium permanganate now? Yeah, well because it would turn an electron donating group into an electron withdrawing group, right? So in other words Right here. What are we going to do? And All right, okay, and what would have been the starting material of that Okay, so a toluene, right And with a nitrogen para to it, right? Okay, so how would we go from? There to there So this is kind of cool because we can say oh, I know how to get from one step to here And I know how to go backwards one step to here now if I can just kind of bridge that gap Then I should be set okay, can anybody figure out and I'm sure you know this reaction, right because we have the methyl group it's going to push that Para the nitro to the para position, right? So what what is it that we use? Okay Okay, so that's how you do that Yeah, thank you, I think we had a better recording of it last time, but this is totally totally awesome Okay, any questions on this one before we get going with it. Okay wonderful
