The material from step 1 of Example 24 (5 g, 0.0117 mol) was suspended in 100 mL absolute EtOH and 60 mL 1N HCl. The mixture was then heated to 80° C. for 18 hours. The heating was then terminated and the compound filtered upon cooling, to give the pure desired product as an orange solid. 3.8 g. (MW=382.35, 85% yield). LC/MS m/z=383.4 (m+1).
