ofp-toluamidine with the condensation product of the chelate with dimethylformamide dimethylacetal results in the formation of 8-(N-benzoyldiaminomethylene)-2-p-tolyl-5,6,7,8-tetrahydroquinazoline-7-one, which is easily debenzoylated by sodium ethoxide. 8-Diaminomethylene-5,6,7,8-tetrahydroquinazolinone derivatives can be used for the preparation of boron chelate complexes.
