Procedure
A solution of chloromethyl chloroformate (2.84 g) in dichloromethane (10 ml) was added dropwise with stirring to an ice-cold solution of 3-(N-tert-butoxycarbonylamino)-propylamine (3.49 g) and diisopropylethylamine (3.10 g) in dichloromethane (30 ml). After stirring for a further 3 hours at room temperature, the mixture was extracted with ice-cold 0.5 M hydrochloric acid followed by water and aqueous sodium bicarbonate. Drying over magnesium sulfate and evaporation in vacuo gave the title compound as colourless crystals.
