Reaction Steps

To ethyl 6-chloro-4-hydroxy-1,1-dimethyl-2-oxo-naphthalene-3-carboxylate (100 mg, 339 μmol, see Example 2) and D-alanine methyl ester hydrochloride (71 mg, 509 mmol) was added 1,4-dioxane (339 μL) and N-ethyl-N-isopropylpropan-2-amine (177 μL, 1018 μmol). The reaction was then heated at 80° C. for 16 hours. The resulting reaction mixture was evaporated to give the title compound (78 mg) as an amorphous solid after purification via preparatory LC. MS m/e=352 (M+1)+.
