실험 절차

A 2.1 g. portion of the 4-hydrazino product of Example 5 was suspended in 130 ml. of water containing 5.4 g. of mercuric oxide and the mixture was stirred at reflux temperature for 4 hours. The mixture was then cooled and filtered, and the solids were triturated with hot ethyl acetate. After filtration, the filtrate was evaporated under vacuum. The residue was redissolved in ethyl acetate-hexane and was chromatographed over a silica gel column with 1:1 ethyl acetate-hexane as the eluant. The second product off the column was the desired product, which was recrystallized from denatured ethanol-water. The yield was 1.0 g. of [1]benzothieno[3,2-d]-v-triazine, m.p. 190°-191° C.
