| abstract | The invention comprises dibenz[bg]tetrahydroazocine, which can be obtained by the cyclisation of 1,3-di-o-aminophenylpropane or one of its salts, e.g. the diphosphate. 2,2-dinitro-chalcone in methanol is reacted with potassium borohydride to give 1,3-di-o-nitrophenyl-3-hydroxyprop-1-ene, which is hydrogenated to 1,3-di-o-aminophenylpropan-1-ol. Treatment of the alcohol with acetic anhydride gives the acetyl derivative, from which 1,3-di-o-acetylaminophenyl-1-chloropropane is obtained with thionyl chloride. Hydrogenation gives 1,3-di-o-acetylaminophenylpropane from which 1,3-di-o-aminophenylpropane is obtained by hydrolysis. According to the Provisional Specification the azocine can be obtained by cyclisation of a compound in which one of the ortho groups is halogen. |
