4953 HERMAN PINES AND JOSEPH T. ARRIGO ... VI. 2,4-Bis-(benzenesulfonyl)-toluene. Condensation with p-Dimethylaminobenzaldehyde .-The sulfone (3.7 g., 0.01 mole) was heated 4 hr. at 145' ~~itli 2 g. of aldehyde and 10 drops of piperidine. Even at this tempera- ture a solid crystalline mass formed, which after a washing with ethanol and crystallization from dioxane formed ;L brick-red powder (2.4 g., 48y0). Recrystallized twice from pyridine, it formed wine-red ...
