4-Butoxybenzoyl chloride → 4-Butoxy-N-[4'-(2,4-dioxothiazolidin-5-ylmethyl)-biphenyl-3-ylmethyl]-N-methylbenzamide

Participants

Reaction Steps

In a manner similar to that of Example 37(e), by reacting 500 mg (1.5 mmol) of 5-(3′-methylaminomethylbiphenyl-4-ylmethyl)thiazolidine-2,4-dione with 290 μl (1.5 mmol) of 4-butoxybenzoyl chloride, and after purification, 550 mg (83%) of 4-20 butoxy-N-[4′-(2,4-dioxothiazolidin-5-ylmethyl)biphenyl-3-ylmethyl]-N-methylbenzamide are obtained in the form of a white solid with a melting point of 116° C.
