The after milling plots are shown in figures 4e and 4f. Figure shows relaxation times of the product, (2) as synthesized. The solvent peak is still visible, at longer T2*(peak A). The T1 of the main peak of the product 2 is 33.2 s and the T2* is 8 µs (peak D). It should be noted that while water is produced as in pathway i, the corresponding peak is not visible due to the presence of the solvent acetonitrile. Figure shows the product after overnight evacuation. The solvent peak is no longer present in this plot (Figure peak A), confirming its identity in Figure . The T1 of the main peak is 38.4 s and the T2* is 10 µs (peak B), indicating production of 2,3-di-p-tolyl-quinoxaline 2.
