The mixture was filtered, and the filtrate loaded onto to an SCX-3 cartridge (10 g) pre-wet with methanol, then washed with methanol and eluted with ammonia in methanol. Product containing fractions were combined and evaporated and the resultant material purified by base modified reverse phase preparative HPLC to yield the title compound as a light orange gum (99 mg, 55%).
