Reaction Steps
In a sealed flask was combined ethyl 8-fluoro-4-hydroxy-2-oxo-2′,3′,5′,6′-tetrahydro-spiro[naphthalene-1,4′-pyran]-3-carboxylate (1.8 g, 5.6 mmol), dioxane (75 mL), tert-butyl 2-aminoacetate hydrochloride (3.8 g, 22 mmol), and N-ethyl-N-isopropylpropan-2-amine (3.9 mL, 22 mmol). The flask was sealed and heated at 90° C. for 10 hours. After cooling to room temperature, the reaction was concentrated to give a solid that was purified by flash chromatography (20% EtOAc/hexane) to afford a white solid (1.9 g). MS m/e=406.1 (M+H)+.
