Procedure
Analogous to Example 1, 2,4,6-tribromophenol was reacted with cyanogen bromide to obtain the title compound as white crystals. The yield was 60% of theory. The product was identified by elementary analysis and its NMR spectrum as well as by the absorption of the cyanato group at 2270 cm-1 in the IR spectrum.
