反应条件: temp:70.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of (5-bromo-2-fluorophenyl)(1-hydroxy-4-methoxycyclohexyl)methanone (Intermediate 12 Step 2, 1.05 g, 3.17 mmol) and potassium tert-butoxide (0.445 g, 3.80 mmol) in THF (10 mL) was heated in a microwave reactor at 70° C. for 30 min. The solvent was removed in vacuo and the residue was purified by flash chromatography using a gradient of 0 to 15% EtOAc in hexanes to afford 388 mg (39% yield) of the title compound. 1H NMR (400 MHz, CDCl3): δ ppm 1.71 (m, 6 H), 2.31 (m, 2 H), 3.32 (m, 1 H), 3.41 (s, 3 H), 7.03 (d, J=9.20 Hz, 1H), 7.36 (t, J=8.80, 2.00 Hz, 1 H), 7.77 (d, J=2.00 Hz, 1 H); MS (ES+) m/z 312 [M+H]|. The solvent was removed in vacuo the residue was purified by flash chromatography
