    • 19. By-products were non-alkylated hydantoin (15%), unknown (35%), and others (25%). Unknown impurities seemed to be resulted from reaction of primary amine with TMOF, because blank experiment (same experimental procedure, only without acetophenone) showed identical unknown peak on GC chromatogram
