Procedure
A solution of methyl ester 351 (250 mg, 0.94 mmol) in AcOH (10 ml) was treated with conc. HCl (5 ml) and the reaction mixture was heated at 120° C. for 2 hrs, cooled and evaporated to produce a solid residue which was re-suspended in water and collected by filtration to afford the title compound (98 mg, 41% yield). LRMS: 251.3 (calcd.), 250.1 [M−H]− (found).
