4-Bromophenol → 4-Bromophenyl phosphorodichloridate

Participants

Reaction Steps

One embodiment of the invention provides a method of preparing AZT-5′-(para-bromophenyl methoxyalaninyl phosphate) in a single reaction vessel without purification of the intermnediates formed. Phosphorous oxychloride is reacted with a para-bromophenol moiety to form para-bromophenyl phosphorodichloridate. Without purification, the para-bromophenyl phosphorodichloridate is contacted with alanine methyl ester to produce para-bromophenyl methoxyalaninyl phosphorochloridate. Without purification, the para-bromophenyl methoxyalaninyl phosphorochloridate is reacted with AZT.
