Procedure

58 μl (0.70 mmol) of allyl bromide are added to a mixture of 162 mg (0.70 mmol) of silver oxide and 200 mg (0.47 mmol) of methyl (S)-3-[3′-(3-heptyl-1-methylureido)biphenyl-4-yl]-2-hydroxypropanoate in 3 ml of diethyl ether. The reaction mixture is stirred at 40° C. for 24 hours. The mixture is filtered and then the solvents are evaporated. The residue is chromatographed on silica gel (heptane/ethyl acetate 80/20 up to 60/40). 180 mg of methyl (S)-2-allyloxy-3-[3′-(3-heptyl-1-methylureido)biphenyl-4-yl]propanoate are obtained in the form of an oil. Yield=82%.
