One- (1-D) and two-dimensional (2-D) carbon-13 NMR exchange measurements in powder samples of isotopically normal durene under magic angle spinning (MAS) are reported. The experiments include rotor synchronized 2-D exchange (RS2DE), 1-D magnetization transfer (MT) and time reverse ODESSA (tr-ODESSA).

A series of N-[(2,3,4,6-tetramethylbenzoyl)alkyl]imidazoles and of N-([beta-(2,3,5,6-tetramethylphenyl)-beta-hydroxy]ethyl)imidazoles has been synthesized. All compounds were tested in mice for anticonvulsant activity against electroshock and pentylenetetrazole convulsions. These durene-derivatives showed good activity, whereas the corresponding benzene-derivatives were inactive.
