    摘要: A process for the preparation of compound of the formula ##STR1## in which R.sup.1 --represents ##STR2## and R.sup.2 --represents hydrogen, fluorine, chlorine or bromine. Comprising cyclizing compounds of the formula ##STR3## and, in a further step, either a) reducing stereo-specifically to give compounds of the formula in which R.sup.1 represents ##STR4## or b), to give compounds of the formula in which R.sup.1 represents ##STR5## or by c) forming compounds of the formula ##STR6## followed by stereoselective reduction to give compounds in which R.sup.1 represents ##STR7##

    摘要: Processes for the preparation of compounds of the formula ##STR1## in which R and R.sup.1 are identical or different and represent hydrogen or halogen, in the racemic form or in the form of its pure enantiomers by cyclicizing compounds of the formula ##STR2## with 2,6-lutidine or by cyclicizing compounds of the formula ##STR3## with diethyl azodicarboxylate. Compounds where R is halogen are new and are useful as cerebral therapeutics, nootropics or in the reduction of increased glutamine pyruvate transaminase in serum.
