Participants

Reaction Steps

In a manner similar to that of Example (5a), by reaction of 574 μl (3.17 mmol, 3 eq) of 4-butoxyphenyl isocyanate and 300 mg (1.06 mmol, 1 eq) of ethyl 3-(3′-methylaminobiphenyl-4-yl)propanoate at 100° C. by microwave for 15 minutes, 490 mg of ethyl 3-{3′-[3-(4-butoxyphenyl)-1-methylureido]biphenyl-4-yl}propanoate are obtained in the form of a white solid. Yield=97%
