Hydroxylamine reacts with 1-alkyl-1,2-dihydro-3,1-benzothiazine-4-thiones (1), giving 1-alkyl-3-hydroxy-2,3-dihydro-1H-quinazoline-4-thiones (2).The same reagent, in neutral medium, converts 1-aryl-1,2-dihydro-3,1-benzothiazine-4-thiones (3) into 1-aryl-4

5H-Benzothiazoloquinazolin-5-ones (Va-d) were synthesized by thermal cyclization of N-(2-benzothiazolyl)-2-fluorobenzamides (IVa-d) which were obtained by allowing 2-fluorobenzoyl chloride to react with 2-aminobenzothiazoles.
