Versuchsvorschrift

Compound 219 (100 mg, 0.29 mmol), compound 221f (242 mg, 0.35 mmol), and potassium carbonate (48 mg, 0.35 mmol) in degassed anhydrous DMF were stirred under microwave radiations at 80° C. for 1 hr. Solvent was removed under reduced pressure and the crude material was purified by chromatography on silica gel (Petroleum ether/DCM) to yield compound 222f as yellow powder in 63% yield. 1H NMR (CDCl3, 400 MHz) δ 1.40 (s, 3H), 1.42 (s, 3H), 2.80 (s, 314), 3.17-3.24 (m, 1H), 3.85 (s, 3H), 3.89 (s, 3H), 5.31 (s, 2H), 6.99 (d, J=9.10 Hz, 2H), 7.00 (s, 1H), 7.21 (m, 1H), 7.31 (d, J=2.93 Hz, 1H), 7.49 (d, J=9.10 Hz, 214), 7.79 (s, 1H).
