Procedure

Diphenyl ether (180 ml) was heated to about 230° C. (Internal temperature 200-210° C.) under inert atmosphere in a round bottom flask fitted with distillation set and a solution of diethyl ({[1-(4-methoxybenzyl)-1H-pyrazol-5-yl]amino}methylidene)propanedioate (85 gm, 0.227 mol) (example 2) in absolute ethanol (130 ml) was added dropwise. The reaction mixture was heated for about 2 hours. Volatile solubles were distilled out. The mixture was cooled to 45° C. and methanol (150 ml) was added dropwise. Solid, which precipitated out was filtered and washed with methanol and hexane and dried under vacuum.
