Determine integration, and splitting you are expecting in the 'H NMR. Step 1: Look at the integration and splitting of the signals in the H NMR spectrum - assign the chemical shift of the protons of the methyl group; make a note which signals in the 'H NMR are due aromatic protons, NH and/or OH. Step 2: Look at the 'HSN HSQC spectrum - Use this spectrum to assign the chemical shifts of the NH proton and the OH proton. Step 3: Look at the 'H1SN HMBC spectrum - Use this spectrum to assign the chemical shifts of the aromatic protons in the 'H NMR. Step 4: Look at the 13C NMR spectrum - Make a note which carbon atoms are aromatic and/or alkyl. Assign the chemical shift of…
