Reaction Steps

The product from Example 5, Step 1 (0.627 g, 2.00 mmol, 1.00 equiv) and cesium carbonate (0.975 g, 3.00 mmol, 1.50 equiv) were combined in DMF (9 mL) for 15 minutes at rt. 3-Methoxybenzyl bromide (0.436 mL, 3.12 mmol, 1.56 equiv) was added and the reaction was heated to 100° C. for 6 hours. The reaction was diluted with H2O and extracted with Et2O. The organic phase was washed with H2O and satd. NaCl, dried over MgSO4 and concentrated en vacuo to provide 0.762 mg (88%) of the title compound as an oil. MS (ES+) m/e 434 [M+H]+
