ظروف التفاعل

الإجراء التجريبي

An 2-anilinesulfonic acid derivative (e.g. sodium 2-anilinesulfonate) or an 3-anilinesulfonic acid derivative (e.g. sodium 3-anilinesulfonate) and aniline are treated with formalin under acidic conditions, to give the corresponding 4,4′-diaminodiphenylmethane derivative. This is diazotized using sodium nitrite under acidic conditions in the presence of hydrochloric acid, followed by reaction with sodium azide, to give the desired product.
