LC-MS Extracted Ion Chromatograms (m/z 559–560) (A) Standards 1 (major) and 5 (minor) (B) Crude microwave reaction in H2O of pure 1 after one minute at 200 °C (C) Crude microwave reaction in MeOH of pure 1 after one minute at 150 °C; the peak at one minute is a result of deliberate overloading of the HPLC column to ensure 5 is not present in that reaction mixture.
