Procedure
Compound 88 was treated with Pyridine HCl (5 g) and heated to 200° C. After 1 hr, the reaction was cooled and diluted with water. The aqueous layer was extracted with EtOAc, dried over MgSO4, and the product was purified by column chromatography (eluant 25% EtOAc/hexanes) to give the product as a solid: (0.025 g, 4.8%); MS 277 [M−H]−
