Reaction Steps

4-Methyl-1-(4-methyl-3-nitro-phenyl)-1H-pyrazole from step 1 was dissolved in EtOH and hydrogenated at room temperature using a hydrogen balloon in the presence of 5% palladium on charcoal. After 20 hours, TLC (EtOAC/Hexanes 1:2) indicated complete reaction. The reaction mixture was filtered through celite and the filtrate was evaporated under reduced pressure to give 2-methyl-5-(4-methyl-pyrazol-1-yl)-phenylamine, MS (M+H)=188.
