Versuchsvorschrift
Another embodiment of the invention provides a method of preparing d4T-5′-(para-bromophenyl methoxyalaninyl phosphate) in a single reaction vessel without purification of the intermediates 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 phosphorodichloridate is reacted with d4T.
