Procedure

To a solution of 4M HCl in dioxane (2 mL) was added compound 10 (0.13 mmol). The reaction mixture was stirred at room temperature for 4 hrs. The mixture was concentrated under vacuum and the solid was dried in vacuo to give compound 11 as a white solid in quantitative yield. 1H NMR (CDCl3, 400 MHz) δ (ppm) 5.26 (s, 2H), 8.20 (s, 1H), 9.92 (brs, 1H), 10.05 (brs, 1H); and MS (ESI, EI+) m/z=218.02-220.03 (MH+).
