Condensed 1,3-Benzothiazinones. 2. Synthesis of 2-Substituted 1,2,4-Triazolobenzothiazin-9-ones

Heating 3-amino-2-imino-3,4-dihydro-2H-1,3-benzothiazin-4-one (1) with formic acid neat or with trimethyl orthoformate (2a) in xylene gave 1,2,4-triazolobenzothiazin-9-one (3a) in 49 and 81percent yields, respectively.An analogous reaction of

Cyanogen condensations as a route to 3 amino 2 imino 1,3 benzothiazin 4 ones with CNS depressant potential

Seven new 3 amino 2 imino 1,3 benzothiazin 4 ones, prepared from the condensation of cyanogen and 2 mercaptobenzhydrazides, were evaluated in a neuropharmacological mouse profile. CNS depression was observed in several members of the class.
