실험 절차

A solution of 24.3 g of (S)-2-(2-methylpropyl)aziridine [Bull. Chem. Soc. (Japan) 35, 1004 (1962).] in 500 ml of ether is treated with 34.2 ml of triethylamine and cooled in ice. While stirring rapidly 40.4 ml (a 10% excess) of benzyl chloroformate is added dropwise over a 30 minute period. After stirring for one hour at 0°, the triethylamine, hydrochloride is filtered off and the ether removed under reduced pressure. The residue is distilled under reduced pressure. After a forerun of benzyl chloride, the product distills at 105°-122°/0.6 mm. There is obtained 51.66 g (90.5% yield) of (S)-2-(2-methylpropyl)-1-aziridinecarboxylic acid, phenylmethyl ester.
