Columned on 11/28/16

The product was columned by the Biotage. The fractions 5-7 (high spots) were combined. The product was a white crystal. Fractions 19-30 were also combined (low spot). NMR was run on the high spot. Initial look suggests that the chlorinated dimethyl product was synthesized with traces of starting material. Ran NMR/GCMS on both high and low spots, shown below.
