    摘要: Compounds are prepared corresponding to the formula ##STR1## WHEREIN R represents hydrogen or methylenethiocyanate (--CH.sub.2 SCN) and each of R.sup.1 and R.sup.2 represents loweralkyl of 1 to 4 carbon atoms. Those compounds wherein R is methylenethiocyanate have been found to be active antimicrobial agents and those wherein R is hydrogen are useful as intermediates therefor.
