Procedure

A mixture of 4-oxo-2-trifluoromethyl-4-(4-trifluoromethyl-phenyl)-thiobutyric acid S-ethyl ester (example C.26 step 4) (16.0 g, 45 mmol) and hydrazine monohydrate (2.39 mL, 49 mmol) in EtOH (250 mL) was refluxed for 18 h under nitrogen atmosphere. Cooled to 23° C., the solvents were evaporated to leave the title compound as a brown solid (13.83 g, 100%), which was used without further purification [according to Synthesis 2003, (3), 436.]. MS (ISP) 311.1 [(M+H)+]; mp 135-136° C.
