“…Interestingly, significant influence of the solvents on isomeric ratio of compound 7d was not detected, in contrast to the work in that have reported cyclocondensation of 1‐benzyldeneamino‐5‐mercapto‐1,3,4‐triazoles with α‐bromoacetophenones giving dihydro triazolothiadiazines.…”

“…Known ( 1 – 6 ) and previously unreported intermediates ( 7 – 11 ) and their precursors were synthesized according to established methods . 2‐(3‐Bromobutoxy)isoindoline‐1,3‐dione ( 12 ) and 2‐(3‐oxobutoxy)isoindoline‐1,3‐dione ( 19 ) were prepared as previously described . Compound 12 was converted into the corresponding alkyliodide 13 by Finkelstein reaction with sodium iodide in acetone.…”
