Procedure

To a solution of Intermediate 346D (0.22 g, 0.450 mmol) in ethanol (2 mL) and water (2 mL) was added NaOH (0.036 g, 0.899 mmol) and the solution was stirred at RT for 16 h. The reaction mixture was concentrated under reduced pressure and the pH of the crude product was adjusted to 2 with an aqueous solution of 1.5N HCl and extracted with EtOAc (2×20 mL). The combined organic layer was dried over anhydrous Na2SO4, filtered and the filtrate concentrated under reduced pressure to afford Intermediate 346E as a white solid (0.12 g, 55%). MS(ES): m/z=462.4 [M+H]+; 1H NMR (400 MHz, DMSO-d6) δ ppm 12.4 (br, s., 1H), 5.55-5.38 (m, 1H), 5.18-5.08 (m, 1H), 4.54 (m, 3H), 1.48 (s, 9H).
