Procedure
A solution of 300 mg (0.703 mmol, 1 eq) of methyl 3-[3′-(3-heptyl-1-methylureido)-2-hydroxybiphenyl-4-yl]propanoate (prepared in Example 15f), 319 mg (2.11 mmol, 3 eq) of 1-chloro-3-iodopropane and 583 mg (4.22 mmol, 6 eq) of potassium carbonate in 10 ml of methyl ethyl ketone is refluxed for 7 hours. The insoluble matter is filtered off, the solvent is evaporated off and the oil obtained is chromatographed on silica gel (35 g FlashSmart column) eluted with 60/40 heptane/ethyl acetate. 394 mg of methyl 3-[2-(3-chloropropoxy)-3′-(3-heptyl-1-methylureido)biphenyl-4-yl]propanoate are obtained in the form of a yellowish oil. Quantitative yield.
