Reaction Steps

Ethyl 3-ethoxyacrylate (0.22 mL, 1.5 mmol) was dissolved in dioxane (4.0 mL) and water (4.0 mL) and after cooling to −10° C., the solution was added with N-bromosuccinimide (0.29 g, 1.6 mmol), followed by stirring at room temperature for 1 hour. The mixture was added with Compound 161 (0.40 g, 1.4 mmol), followed by stirring at 80° C. for 1 hour. The reaction mixture was added with aqueous ammonia to stop the reaction. The precipitated crude product was collected by filtration, purified by silica gel column chromatography (hexane/ethyl acetate=4/1 to 1/2) and triturated in ethyl acetate to obtain Compound 165 (45 mg, 8%).
