The reaction of 2-isothiocyanatodesoxybenzoine prepared from 2-aminodesoxybenzoine and thiophosgene in good yield and 2-aminoethanol or methylhydrazine supplied a 4-hydroxy-1,2,3,4-tetrahydroquinazoline and an open chained thiosemicarbazide derivative, respectively. When heating, both compounds react under loss of water. The latter forms the 5-benzyl-3-methyl-2-thioxo-2,3-dihydro-1H-1,3,4-benzotriazepine which can be alkylated at the sulphur atom and transformed into the 2-oxo analog.
