実験手順

This exemplified compound may be readily synthesized by the reaction of methyl isocyanate with hydrazine to give 4-methyl-3-thiosemicarbazide followed by cyclocondensation with trifluoroacetic acid as described in U.S. Pat. No. 4,477,459. This compound may also be prepared by the reaction of 4-methyl-3-thiosemicarbazide with trifluoroacetylfluoride and heat (U.S. Pat. No. 3,780,052).
