Reaction Steps
The sodium salt of 5-formyl-2-methylbenzenesulphonic acid used as starting material for the bis-stilbene compound of the formula (88) is obtained by sulphonating 4-methylbenzaldehyde with oleum containing 66% of SO3 and purification via the barium salt. In a similar manner the sodium salt of 5-formyl-2methoxybenzenesulphonic acid, used as starting material for the bis-stilbene compound of the formula (89), is obtained from 4-methoxybenzaldehyde. ##SPC61##
