Melting points were measured
on an Electrothermal melting point apparatus and are uncorrected.
Analytical reversed phase HPLC was run on a Waters
600 HPLC photodiode array system using an Alltech Rocket
C18 column (3 mm Econosphere, 337 mm) and eluting with
a linear gradient of H2O (0.05% TFA) through to MeCN.
