Versuchsvorschrift
A suspension of compound vii (0.140 g, 0.410 mmol) in aqueous sodium hydroxide solution (2M, 3 mL) was heated to 75° C. for 48 h, cooled to 0° C. and acidified to pH ˜2 using concentrated hydrochloric acid (35%). The resulting colourless precipitate was filtered, washed with water (3 mL) and air dried to give the desired compound viii. (0.116 g, 0.369 mmol, 90%) as a colourless powder, 1H NMR (300 MHz, DMSO-d6): δ 9.98 (1H, br s), 9.17 (1H, br s), 8.58 (1H, s), 7.94 (1H, br t), 7.30 (1H, t, J 7.7), 7.20 (1H, s), 7.12-7.06 (2H, m), 7.01 (1H, d, J 7.7), 3.13 (2H, dq, J 6.7 and 7.7), 1.05 (3H, t, J 7.2); [M+H]+ m/z=315.1.
