Conclusions
-
1.
The reaction of 6-methyluracil with dibutyl 4-chlorobutylphosphonate leads to the formation of 1,3-bis-[4′-dibutylphosphono)butyl]-6-methyluracil.
-
2.
The reaction of 2-amino-4-hydroxy-6-methylpyrimidine with dibutyl 4-chlorobutylphosphonate leads to the formation of a mixture of 2-amino-4-[4′-(dibutylphosphono)butyl]oxy-6-methylpyrimidine and the dibutyl ester of 4′-(2-amino-4-oxo-6-methyl-3,4-dihydro-3-pyrimidinyl)-butylphosphonic acid.
