Procedure

A solution of the product obtained in step 2 (0.5 g, 2.23 mmol) in AcOH (2.5 mL), H2O (2.5 mL) and concentrated H2SO4 (2.5 mL) was refluxed for 5 h. After cooling, the reaction mixture was adjusted with 10 N NaOH to pH=10 and washed with AcOEt. The aqueous layer was acidified with concentrated HCl to pH=1 and then extracted with AcOEt. The organic phase was washed with H2O, dried over Na2SO4 and evaporated under reduced pressure. The crude product was used in the following step without further purification.
