in neat (no solvent) byproducts: hydrogen, pyrazol-1-ylpyrazaboles; a mixt. of PhNHMe and pyrazabole in 4:1 molar ratio was refluxed under Ar for 28 h; cooled to room temp., washed several times with toluene, residue was identified as N(NMePh)3 (NMR, IR, MS), the toluene washings were evapd., residue was shown to be a mixt. of pyrazol-1-ylpyrazaboles (primarily tetrakis substituted one) by NMR;
