110-70-3, Rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions.110-70-3, name is N1,N2-Dimethylethane-1,2-diamine, below Introduce a new synthetic route.
EXAMPLE 12 N-Boc-N,N’-dimethylethylene diamine N,N’-dimethyl ethylenediamine (8.8 g) was dissolved in 200 ml tetrahydrofuran and to this was added over a 10 min period di-t-butyldicarbonate (4.36 g) in 30 mL tetrahydrofuran. 72 hours later, the solvent was evaporated and the residue partitioned between ether and KHCO3 and the organic layer was dried (MgSO4) and evaporated to give 11.6 g title compound (58% yield). 300 MHz 1 H NMR was consistent with proposed structure.
