A mixture of 10.85 g. (0.05 m.) of the compound of Example I, C., 7.6 g. (0.05 m.) of 4-methyl-3-nitroaniline and 500 ml. of ethanol was refluxed overnight. The reaction mixture was concentrated in vacuo to give 38 g. of crude product. It was then dissolved in 6000 ml. of MeOH and filtered hot. The MeOH filtrate was concentrated in vacuo to yield 27 g., m.p. 344°-345°C.
