Xc. Wang et al., Synthesis of 2-aroylamino-5-aryloxymethyl-1,3,4-thiadiazoles under liquid-liquid phase transfer catalysis, SYN COMMUN, 31(9), 2001, pp. 1447-1452
2-Aroylamino-5-aryloxymethyl-1,3,4-thiadiazoles (I1-20) are synthesized by
the condensation of 2-amino-5-aryloxy-methyl-1,3,4-thiadiazoles with aroyl
chlorides in the presence of PEG-400 phase transfer catalyst.
