実験手順
Sodium bicarbonate (1.7 g, 0.02 mole) and glycine ethyl ester hydrochloride (1.4 g, 0.01 mole) were dissolved in water (10 ml) and a solution of 2,3-dimethyl-2-isopropylbutanoyl chloride (1.6 g, 0.009 mole) in ether (10 ml) was added. The mixture was stirred vigorously at room temperature for 2 hours. After 16 hours at room temperature the ether layer was separated and dried (MgSO4). Removal of the solvent left a white solid which was recrystallised from ether/petroleum ether to give N-(2,3-dimethyl-2-isopropylbutanoyl)glycine ethyl ester, mp. 74.5°-75.5°.
