REGIOSELECTIVE CYCLIZATION OF S-ACRYLIC ACID DERIVATIVE OF 1,2,4-BENZOTRIAZINE TO 10H-[1,3]THIAZIN0 [2,3-C][1,2,4] BENZOTRIAZIN-4-ONE

3-Mercapto-1,2,4-benzotriazine was condensed with propiolic acid to afford the S-acrylic acid derivative 2. The latter was regioselectively cyclized to 10H-[1,3) thiazino [2,3-c][1,2,4]benzotriazin-4-one 3.
