Condensation of 4-bromoacetylbiphenyl (I) with N-methyl ethanolamine (II) leads to the 2-hydroxymorpholine (III). The acid-catalyzed reaction of the hemiketal (III) with 3-bromo-1-propanol (IV) gives the bromopropoxy morpholine (V), which is finally converted into the title nitrate ester by treatment with AgNO3 in acetonitrile.
