Reaction Steps

To a warm solution of 3.3 g. of the diketone of Step A in 33 ml. of ethanol and 10 ml. of chloroform is added 4 g. of hydrazine and the resulting solution is refluxed for 1 hr. It is then cooled and evaporated to dryness under reduced pressure. The crude solid residue obtained is crystallized from methanol to yield the product 3-(p-tolyl)-4H-indeno[1,2-c]-pyrazole (m.p. 250°-252°C).
