4-Methylbenzoyl Chloride → N'-[(4-methylphenyl)carbonyl]-3-nitrobenzohydrazide

Participants

Reaction Steps

To a solution of 3-nitrobenzhydrazide (2.16 g, 11.92 mmol) in pyridine (40 ml) cooled to 0° C. in an ice bath is added dropwise p-toluoyl chloride (1.94 g, 11.92 mmol). The mixture is allowed to warm to room temperature and stirred for 12 hours. The mixture is quenched with 350 mL of water and stirred for thirty minutes. The precipitate is filtered and dried in a vacuum oven to yield 1-[(4-methyl)benzoyl]-2-(3-nitrobenzoyl)hydrazine as a pale yellow solid. (2.94 g, 82%). 1H MMR (DMSOd6): δ 2.40 (s, 3H), 7.35 (d, 2H), 7.86 (d, 2H), 7.87 (t, 1H), 8.37 (d, 1H), 8.45 (d, 1H), 8.76 (s, 1H), 10.58 (s, 1H), 10.90 (s, 1H).
