The protection of 5-amino-1-pentanol (I) gives the fully protected compound (II), which is condensed with propenal (III) yielding the 3-aminopropanal derivative (IV). The condensation of aldehyde (IV) with phosphorane (V) yielded the protected 5-amino-2-bromopentenoic ester derivative (VI), which is deprotected with trimethylsilyl triflate to afford the ester (VII) with an unprotected secondary amino group.
