Versuchsvorschrift
A solution of Intermediate 12D (25 g, 84 mmol) in DCM (330 mL) and TFA (330 mL) was stirred at rt. After 1.5 h, the solvent was concentrated to give Intermediate 12 (19.5 g, 97.0% yield) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ: 12.69 (bs, 1 H), 7.80-7.76 (m, 2 H), 7.62 (d, J=12.1 Hz, 1 H), 6.30 (dd, J=2.4, 2.0 Hz, 1 H), 2.6 (s, 3H) ppm. MS (ESI) m/z: 241 (M−H)+.
