Procedure
Compound 16 (0.735 g, 3.50 mmol, 1.00 eq) was dissolved in ethanol (15 mL) and 1N NaOH (7.5 mL) was added. The mixture was refluxed for 18 h and after cooling the reaction was neutralized with 1N HCl (7.5 mL) and the reaction was concentrated in vacuo. The crude reaction was dissolved in 10% MeOH/CH2Cl2 and the undissolved salt was filtered off and the solvents were removed in vacuo to afford 0.710 g (89%) of the title compound as an off-white solid: 1H NMR (400 MHz, CDCl3) δ 8.70 (s, 1H), 8.45 (s, 2H), 7.69-7.64 (m, 2H), 7.48 (t, J=8.3 Hz, 1H), 7.43-7.39 (m, 1H), 3.34 (s, 3H); [M+1]+: 230.2.
