Procedure

22 g of the above wet filter cake (0.039 mol) was suspended in 11 g H2O and titrated with 16 ml (0.032 mol) of 2M Na2CO3 to a pH of 5.27 at 55° C. This corresponds to 94% of theoretical base for the neutralization of (tolyltriazole)2.H2SO4. The weight of isolated tolyltriazole was 8.47 g (0.064 mol) as a white solid. This corresponds to a 94% yield.
