Procedure:
A stirred solution of 2.4 grams (0.011 mole) of 1-methoxy-2- cyano-6-phenyl-1-hexene, 4.2 grams (0.044 mole) of guanidine hydrochloride, and 7.6 grams (0.055 mole) of potassium carbonate in 40 mL of N,N-dimethylformamide was heated at 100° C. to 105° C. for about 20 hours. After this time the reaction mixture was diluted with 100 mL of water. The mixture was then extracted with two 100 mL portions of ethyl acetate. The combined extracts were washed with three 75 mL portions of an aqueous 10% lithium chloride solution. The organic layer was dried with sodium sulfate and filtered. The filtrate was concentrated under reduced pressure to a residual oil. The residue was subjected to column chromatography on basic alumina that was deactivated to Level III with water. Elution was accomplished with 1% to 3% methanol in methylene chloride.

Procedure:
2-Ethoxy-3-{4-[2-(4-hydroxyphenyl)ethoxy]phenyl}propanoic acid ethyl ester (described in Example 26b) (0.36 g; 1.0 mmol) was dissolved in dry dichloromethane (25 ml) and benzylisocyanate (0.20 g; 0.185 ml; 1.5 mmol) was added followed by addition of triethylamine (0.22 ml; 1.5 mmol). The solution was stirred at room temperature for 3 hours.

The crude material was purified on preparative reversed phase HPLC using a gradient of acetonitrile-water-ammonium acetate as mobile phase. Fractions containing pure product were pooled and the acetonitrile removed in vacuum. The residue was dissolved in dichloromethane, washed with water, dried with sodium sulfate and evaporated to give 0.23 g (48%) of pure 3-{4-[2-(4-benzylcarbamoyloxyphenyl)ethoxy]phenyl}-2-ethoxypropanoic acid ethyl ester

Procedure:
Under nitrogen bubbling, a mixture of 2-(3-chlorophenyl)-3H-imidazo[4,5-b]pyridine-3-acetic acid (2.38 g, 0.008 mole) and 1,1'-carbonyldiimidazole (1.34 g, 0.008 mole) was stirred at room temperature for 3 hours. The N,4-dimethyl-1-piperazinepropanamine (1.42 g, 0.008 mole) was added and the reaction mixture was allowed to stir at room temperature for 2 hours. The reaction mixture was evaporated to dryness. The residue was partitioned between methylene chloride and aqueous potassium bicarbonate. The aqueous layer was separated and extracted with methylene chloride. The methylene chloride layers were combined, extracted with aqueous potassium bicarbonate and water and dried over sodium sulfate. The filtrate was evaporated and the solid residue was recrystallized as a fumarate salt from ethyl alcohol-isopropyl ether. Recrystallization from isopropyl alcohol-acetonitrile-isopropyl ether did not improve the analysis. The solid was converted to the free base. The free base was treated with boiling hexanes and allowed to cool to room temperature. The solid was collected by filtration, washed with hexane, and dried under high vacuum overnight to give 0.7 g of title compound, mp 114°-17° C.
