Reaction Steps

Proceeding in a manner similar to that described in Example 1 above substituting for ethyl alcohol and the concentrated hydrochloric acid the appropriate reaction medium and the appropriate catalyst listed in Examples 58-82 of Table A hereinbelow, 4-dimethylaminobenzaldehyde, sodium p-toluenesulfinate and 1-ethyl-2-methylindole were interacted at the indicated temperature to obtain a methane of Formula II wherein R=4--CH3 ; R1 =C2H5 ; R2 =CH3 ; R3 =R5 =H; R6 =N(CH3)2. A toluene or acetone solution of the product from Examples 58-82 contacted with silica gel developed a blue-red colored image.
