Procedure

To a suspension of 4-(5-amino-1,3,4-thiadiazole-2-yl)-2,6-bis(1,1-dimethylethyl)phenol (1.5 g, 0.005 mole) in tetrahydrofuran (10 ml) is added ethoxycarbonylisothiocyanate (0.64 g, 0.005 mole) dropwise. The resulting mixture is stirred 18 hours at room temperature, before concentrating in vacuo. The residue is recrystallized from ethanol/water to provide 1.7 g (2.2 g theor., 78%) of the title compound after drying in vacuo at 50° C., mp >25° C.
