Procedure

The process of Example 2 was followed in general, using 4.4 g. of 3-amino-4-nitrobenzo[b]thiophene-2-carbonitrile and 1.7 g. of sodium nitrite in 60 ml. of concentrated hydrochloric acid and 60 ml. of glacial acetic acid. The product was recrystallized from a dimethylformamide, and the yield was 4.0 g. of purified 4-chloro-9-nitro[1]benzothieno[3,2-d]-v-triazine, m.p. 171°-173° C.
