Reaction Steps

The product of Example 123B (1 equiv), potassium tert-butoxide (1.1 equiv) and 2-bromoethyl methyl ether (1 equiv) were combined in DMF (0.1 M) and heated in a SmithSynthesizer™ microwave at 250° C. for 15 minutes. The mixture was diluted with EtOAc and washed with 1 M aqueous NaHCO3. The phases were separated and the aqueous phase was extracted with EtOAc (3×). The combined organic extracts were dried over Na2SO4, filtered, and concentrated. Purification by silica gel chromatography afforded the title compound and the product of Example 124. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.20 (s, 6H), 1.26 (s, 6H), 1.57 (s, 1H), 3.10 (t, J=7.5 Hz, 2H), 3.23 (s, 3H), 3.26 (t, J=7.4 Hz, 2H), 3.71 (t, J=5.8 Hz, 2H), 4.67 (t, J=5.8 Hz, 2H); MS (ESI+) m/z 377 (M+H)+.
