Procedure

A solution of 2.4 g. (0.009 mole) of the above hydrochloride in 50 ml. of 50% aqueous sulfuric acid was cooled to 0° C. and treated with a solution of 0.97 g. (0.014 mole) of sodium nitrite in 10 ml. of water. The mixture was stirred at 0° C. for two hours, poured into ice water, treated with charcoal, filtered, basified with ammonium hydroxide and extracted with ether. The combined ether extracts were dried, treated with charcoal, filtered and partly concentrated to yield [1,2,3]thiadiazolo[4,5-h]isoquinoline, melting point 150°-153° C.
