An easy and efficient method for the synthesis of novel deoxycholic acid bis-1,3,4-thiadiazol-carbamate derivativesundermicrowaveirradiation has been developed. Twelve new methyl 3α,12α-bis-[(5-aryl-1,3,4-thiadiazol-2-yl) carbamoyloxy]-cholan-24-oates were obtained in better yield (78–91%) and shorter time (15–22 min). Their structures were identified by 1H NMR, IR, MS spectra and elemental analyses
