Reaktionsschritte

3-Methylbutane-1,3-diol (42 mg, 0.4 mmol) in THF (1 mL) was treated with NaH (60%) (16 mg, 0.4 mmol) at room temperature for 20 min. To the above mixture, which was cooled to 0-5° C., was added the product from Example 20B (80 mg, 0.2 mmol) in THF (1 mL). After 20 min. the reaction mixture was quenched with saturated aqueous NaHCO3 (20 mL) and extracted with ethyl acetate (2×30 mL). The combined organic extracts were dried over anhydrous Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by column chromatography using an Analogix® Intelliflash280™ (SiO2, 0-100% ethyl acetate in hexanes) to afford 87 mg (90%) of the title compound. 1H NMR (500 MHz, CDCl3) δ ppm 1.04 (t, J=7.32 Hz, 3H) 1.36 (s, 6H) 1.47-1.55 (m, 2H) 1.88-1.96 (m, 2H) 2.13 (t, J=5.80 Hz, 2H) 4.35 (t, J=5.80 Hz, 2H) 4.54 (t, J=7.63 Hz, 2H) 5.12 (brs, 1H) 7.11 (d, J=8.54 Hz, 1H) 7.61 (d, J=5.19 Hz, 1H) 7.74 (dd, J=8.54, 2.14 Hz, 1H) 8.49 (d, J=5.19 Hz, 1H) 8.68 (s, 1H) 8.72 (s, 1H); MS (ESI+) m/z 482 (M+H)+.
