A method has been developed for the synthesis of linear 5,6-benzindole by reduction of N-acetyl-5,6-benzindoxy with NaBH/sub 4/ and subsequent hydrolysis of the N-acetyl group. The PMR spectra were obtained on a Varian H-100 spectrometer in solutions of acetone-d/sub 6/ and chloroform-d/sub 3/ with TMA as internal standard. IR spectra were recorded on a Perkin-Elmer 180 spectrometer in KBr disks or in chloroform solutions in standard cells. TLC was conducted on Silufol UV-254 plates, with chloroform as eluent.
