実験手順
75 parts of 2-phenyl-4-amino-5-cyanothiazole in 300 parts of dimethylformamide and 15 parts of triethylamine are reacted with 13 parts of hydrogen sulfide as described in Example 1(a). 77 parts of 2-phenyl-4-amino-5-thiocarbamoylthiazole (89% of theory) of melting point 164°-167° C. are obtained.
