Diethyl(N-arylaminocarbonyl)methyl phosphonates have been obtained by the reaction of diethylphosphonoacetic acid imidazolides with methyl-4-aminobenzoate or 3,5-bis(trifluoromethyl)phenylamine. Their treatment with Me3SiBr in DMF led to a mixture of the corresponding (N-arylaminocarbonylmethyl)phosphonic acids and their monoethyl esters. After separation, they were condensed with 3'-O-acetyl-alpha-thymidine, which, after the removal of the acetyl protecting group, gave (alpha-D-thymidine-5'-yl)-[4-aminocarbonyl-, methoxycarbonyl-, or carboxy)phenylaminocarbonyl]methyl phosphonates and (alpha-D-thymidine-5'-yl)-[3,5-bis(trifluoromethyl)phenylaminocarbonyl]methyl phosphonate and their ethyl esters. It was shown that the compounds are stable under different conditions, low toxic (in Vero and K-562 cell cultures), and capable of penetrating into K-562 cells. Only ethyl (alpha-D-thymidine-5'-yl)-[4-(methoxycarbonyl)phenylaminocarbonyl]methyl phosphonate at a high concentration (200 mu g/mL) inhibited in vitro the growth of the laboratory strain M. tuberculosis H37Rv.
