Procedure

Ten and three tenths grams of 86.4 percent sodium p-toluenesulfinate, 10.7 g of 90.7 percent N,N-diethyl-3-ethoxyaniline and 12 g of 4-(N-ethyl-N-benzyl)-aminobenzaldehyde were interacted in the presence of 18.2 g of 95 percent methanesulfonic acid to obtain a methane of Formula XV wherein R=4--CH3 ; R5 =C2H5O; R6 =N(C2H5)2 ; Q=4--[(C2H5)(C6H5CH2)NC6H4 ], an oil. A significant infrared maximum appeared at 1145 (SO2 ; s) cm-1. The product developed a violet colored image.
