Reaction Steps

A solution of ethyl 6-chloro-1-(4-chlorophenyl)-4-hydroxy-1-methyl-2-oxo-naphthalene-3-carboxylate (0.998 g, 2.55 mmol), glycine tert-butyl ester hydrochloride (0.513 g, 3.06 mmol), and DIPEA (0.889 mL, 5.10 mmol) in 1,4-dioxane (15 mL) in a 75 mL sealed vessel was stirred at 120° C. for 3 hours. The solution was diluted with deionized water (75 mL) and extracted with DCM (2×50 mL). The combined organic layers were then washed with brine (50 mL), dried over MgSO4, and concentrated in vacuo to give 1.42 g crude product. The crude product was purified by flash column chromatography (silica, 0-25% DCM in hexane) to give the title compound (0.888 g). MS m/e=420 (M+H-tBu)+.
