Reaction Conditions

Temperature80 °C

Reaction Steps

A mixture of the product from Example 46, Part D (0.100 g, 0.382 mmol), N-methylmethane-sulfonamide (45.9 mg, 0.421 mmol) and potassium carbonate (0.127 g, 0.918 mmol) in N,N-dimethylacetamide (5 mL). The mixture was stirred at 80° C. for 11 h, cooled to room temperature and partitioned between diethylether and water (3×), dried overmgSO4, filtered and concentrated in vacuo to give the title compound as a colorless waxy solid (0.128 g, quant.).
