N-Alkylation of primary alkyl bromides with diethyl N-sodio-N-(t- butoxycarbonyl)phosphoramidate 1 carried out in boiling acetonitrile in the presence of 10mol% of tetrabutylammonium bromide as catalyst leads to the corresponding N-alkyl derivatives 2a-I. Deprotection of 2 by refluxing with p-toluenesulfonic acid in ethanol-affords ammonium tosylates 3a-I in reasonable yields.
