Versuchsvorschrift

Compound 222f (1.23 g, 2.82 mmol), cesium trichloride (1.58 g, 4.23 mmol), and sodium iodide (423 mg, 2.82 mmol) in ACN (26 mL) were stirred at 85° C. for 1 hr. The mixture was then filtered through celite and the solvent was evaporated. The brown solid obtained was suspended in water, pH was adjusted at 5 with 1N HCl. The mixture was extracted with DCM, dried over Na2SO4, filtered, concentrated under reduced pressure, and purified by chromatography on silica gel (petroleum ether/DCM) to yield compound 218f as a brown solid in 55% yield. 1H NMR (CDCl3, 400 MHz) δ (ppm) 1.40 (d, J=6.91 Hz, 6H), 2.80 (s, 3H), 3.17-3.24 (m, 1H), 3.89 (s, 3H), 7.00 (s, 1H), 7.21 (m, 1H), 7.55 (s, 1H), 7.79 (s, 1H), 9.56 (brs, 1H).
