Versuchsvorschrift
N-Methyl 4-nitrobenzamide (30.0 g, 167 mmole) and thionyl chloride (256 g, 2.15 mole) were heated at reflux for five hours. The excess thionyl chloride was removed at ~15 mm Hg. Xylene was added to the reaction and distilled under reduced pressure to yield a solid which was recrystallized from petroleum ether to yield 8.6 g of the title compound as a light yellow solid, m.p. 67°-73° C.
