Reaction Steps
1.0 g 1-bromo-naphthalene-2-carboxylic acid and 0.61 g 2,2-dimethylglycine methyl ester hydrochloride were suspended in 30 ml of dichloromethane and 10 ml of DMF. 1.31 ml N-methylmorpholine, 0.70 g 1-hydroxybenzotriazole and, finally, 0.99 g 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride were added and the reaction stirred at room temperature for 14 h. The reaction mixture was chromatographed on silica (ethyl acetate/heptane) without aqueous work-up to give 1.3 g 2-[(1-bromo-naphthalene-2-carbonyl)-amino]-2-methyl-propionic acid methyl ester.
