The title compound was prepared according to the procedure in Henbach, DE 2724891 A1, 1978, with modifications to three steps: In the addition of the aniline, 4-nitroaniline was used instead of 3,5-dichloroaniline and dry THF was used as solvent instead of toluene. In the formation of the triazolinone ring, triphosgene (0.65 equiv) was used instead of phosgene: mp 136-140° C.; 1H NMR (300 MHz, CDCl3) δ 8.40 (d, J=8.8 Hz, 2H), 8.05 (d, J=8.8 Hz, 2H), 7.99 (s, 1H), 7.89 (d, J=9.3 Hz, 2H), 7.32 (d, J=9.3 Hz, 2H); ESIMS m/z 367 (M+H).
