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-1. Deprotection of 2 by refluxing with p-toluenesulfonic acid in ethanol affords ammonium tosylates 3a-1 in reasonable yields.
