2-Bromo-l-indanol (I) reacts with ethanolamine to give 2~hydroxy-l~(β - hydroxy) ethylamin-oidane (II). Attempt cyclisation of II by 70% aqueous sulphuric acid afforded 1 -ethenylamino-2-hydroxyindane (III). Benzoylation of III gave l-(N-benzoyl) ethenylamino- 2-benzoyloxyindane (IV). I reacts with semicarbazide hydrochloride to give (1,2-e)-indano-2-imino-2, 3, 4, 5, 6-pentahydro-I, 3, 4-oxadiazine (V). However, reaction of I with benzylamine or isobutylaminc gave l-benzylamino-2-hydroxyindane (VI) or 1-isobutylamindane (VII), respectively. The structure of the products was assigned on the basis of the spectra of n. m. r., mass and infrared as well as analytical data.
