## Abstract 4‐Aminopyrazole‐3‐ones **4b, e, f** were prepared from pyrazole‐3‐ones **1b‐d** in a four‐step reaction sequence. Reaction of the latter with methyl __p__‐toluenesulfonate gave 1‐methylpyrazol‐3‐ones **2b‐d**. Compounds **2b‐d** were treated with aqueous nitric acid to give 4‐nitropyraz
