Reaction Steps

464 μl (2.55 mmol, 1.5 eq) of octyl isocyanate are added to 482 mg (1.7 mmol, 1 eq) of ethyl 3-(3′-methylaminobiphenyl-4-yl)propanoate (prepared in Example 7c). The reaction mixture is heated at 100° C. by microwave for 30 minutes. The residue is chromatographed on silica gel (50 g FlashSmart Pack column) eluted with 70/30 heptane/ethyl acetate. 755 mg of ethyl 3-[3′-(3-octyl-1-methylureido)biphenyl-4-yl]propanoate are obtained in the form of a yellowish oil. Yield=100%
