A solution of tetramethylammonium hydroxide dihydrate (TMA(H)·2H2O) (1.8 g, 14.0 mmole), benzamide (1.2 g., 9.9 mmole) and 10 ml of xylene was stirred under nitrogen at 70° C. Thewater and xylene was removed by vacuum distillation at 740 mmHg/70° C. Nitrobenzene (1.2 g., 9.7 mmole) was added dropwise and the solution was stirred for 4 hours under nitrogen after which time an aliquot was removed for HPLC analysis. 4'-Nitrobenzanilide, i.e., N-(4-nitrophenyl)benzamide, was produced in 98% yield based on benzamide. Azoxybenzene was also detected as a minor product in this reaction.
