An unambiguous total synthesis of the title compound, a semi-synthetic derivative reported to be a non-nucleoside reverse transcriptase inhibitor, was conducted in four steps from 2,5-dimethoxyaniline. The synthetic material differed from that reported in the literature, both in its physical properties and 1 H NMR spectrum. Biological evaluation indicated that synthetic 2 was inactive against HIV-1 RT, suggesting that the previous structural assignment of the semi-synthetic derivative was incorrect.
