Reaction Steps

To a heterogeneous mixture of 4-chloro-thiobenzoic acid hydrazide (0.107 mmol) in CH2Cl2 (1 mL) is added 2-difluoromethoxy-benzaldehyde (0.128 mmol) and DIEA (0.128 mmol). After 10 minutes the mixture become homogenous and the reaction is complete by TLC and LCMS to give 5-(4-chloro-phenyl)-2-(2-difluoromethoxy-phenyl)-2,3-dihydro-[1,3,4]thiadiazole which is used in the next step without evaporation of the solvent.
