So first off I'm new here! My name's Jordan. I'm looking for a forum to help me in my quest to get to know as much chemistry as I can and to get help for projects I wish to do from people who know what they're talking about. So anyway here's my question: So recently I have successfully synthesized Serotonin! With this success I thought it might be fun to make some other neurotransmitters. Right now Dopamine is my next product, which shouldn't be to hard to do. I think I got the idea on how to do that. Just a Decarboxylation of L-DOPA and that should be very easy. But then I realized that with the Dopamine I could also use it to make Norepinephrine. I'm still a very nooby chemist and thought I'd ask for help on this wonderful forum. So my question is what's the best way to add an OH to the Dopamine to make Norepinephrine. If I had to guess it shouldn't be that hard. But I honestly have no idea. If anyone can give some details on how I can do this or point me to something that would help I'd be very grateful! Hope you're all having a wonderful week
