Procedure

To a suspension of 3.2 g. (0.01 mole) of 1-(4-chlorophenyl)-4-methoxypyridinium fluorosulfonate, prepared by the process set forth in Example 1, in 20 ml. methanol was added 0.4 g. anhydrous hydrazine. The mixture was heated to boiling for a few minutes and the resulting clear orange solution was kept overnight at room temperature. The product, in the form of orange crystals, was obtained in two crops. The total weight was 2.97 g. (93%). The product was recrystallized from methanol, m.p. 174°-176° C. The elemental analyses for C, H, N and Cl were within ±0.4% of the theoretical values.
