실험 절차

To a solution of Example 81D (7.6 g, 84 mmol) in THF (300 mL) at 0° C. was added potassium tert-butoxide (18.9 g, 168 mmol). The ice bath was removed and the mixture was stirred for 45 min then a solution of Example 81C (22.4 g, 56.1 mmol) in THF (100 mL) was added. The mixture was stirred for 2 hours at ambient temperature then partitioned between saturated aqueous NaHCO3 (100 mL) and EtOAc (100 mL). The layers were separated and the aqueous phase was extracted with EtOAc (3×20 mL). The combined organic extracts were dried over anhydrous Na2SO4, filtered, and concentrated under reduced pressure. Purification by column chromatography (SiO2, 50% hexanes/EtOAc then 100% EtOAc then 9:1:0.1 EtOAc:MeOH:Et3N) afforded the title compound (15 g, 31.9 mmol, 57% yield). 1H NMR (300 MHz, CDCl3) δ ppm 0.95 (t, J=7.3 Hz, 3H) 1.28 (s, 6H) 1.32-1.42 (m, 2H) 1.42 (s, 9H) 1.61-1.72 (m, 2H) 3.75 (s, 3H) 4.03 (s, 2H) 4.27 (dd, J=7.8 Hz, 2H) 6.16 (s, 1H) 7.00 (d, J=8.5 Hz, 1H) 6.99 (s, 1H) 7.51 (dd, J=8.6, 1.9 Hz, 1H) 8.13 (d, J=2.4 Hz, 1H); MS (DCI/NH3) m/z 470 (M+H)+; Anal. calculated for C24H34F3N3O3: Calc: C, 61.39; H, 7.30; N, 8.95. Found: C, 61.33; H, 7.38; N, 8.91.
