Procedure
Title compound 13 (3.65 g, 14.7 mmol) was dissolved in DMF (25.0 mL) and sodium hydroxide (0.706 g, 17.7 mmol) was added. The reaction mixture was stirred at 130° C. for 5 hours. The mixture was cooled down to room temperature and an ice/water mixture was added. The precipitate was filtered then triturated in ethanol to afford title compound 14 (1.798 g, 58%) as a white solid. LRMS (ESI): (calc) 212.06 (found) 213.2 (MH)+.
