Procedure

A stirred mixture of 3-nitro-1,2-phenylenediamine (1.00 g, 6.53 mmol) and p-toluenesulfonyl chloride (1.25 g, 6.53 mmol) in pyridine (50 ml) was heated at reflux for 1 h, then concentrated to dryness in vacuo to give the title compound in sufficient purity for use in the next step. MS: m/z=308 (M+1).
