The use of sodium hydrogen carbonate under solvent-freeconditions and microwave irradiation is by far the best method for N-alkylating pyrazoles. The yields are good and the method is devoid of side reactions (quaternization, isomerization, hydrogen halide elimination). Solvent-freeconditions are the only ones that allow us to prepare 1-substituted pyrazoles from secondary halides. The procedure using
