Reaction Steps

To 0.2 g of 4-fluoro-1-[4-(trifluoromethyl)benzyloxy]naphthalene-2-carboxylic acid, 158 mg of EDC, 104 mg of 1-hydroxybenzotriazole and 102 mg of 2,2-dimethylglycine methyl ester hydrochloride was added 5.3 ml of DMF followed by 0.29 ml of diisopropylethylamine. The mixture was stirred for 16 h at room temperature. The mixture was poured into cold water, acidified to pH 2-3 with 1M HCl, extracted with ethyl acetate, washed with water, brine, dried (sodium sulphate) filtered and concentrated to an oil. The material was flash chromatographed on silica gel eluting with ethyl acetate/heptanes to provide 0.207 g of 2-{[4-fluoro-1-(4-trifluoromethyl-benzyloxy)-naphthalene-2-carbonyl]-amino}-2-methyl-propionic acid methyl ester as a colorless oil.
