Reaction Conditions

Reaction Steps

A mixture of 3-{4-[cyclohexyl(hydroxy)methyl]-5-methylfuran-2-yl}benzamide (0.6 g), ethyl 3-{[(4-aminophenyl)carbonyl](methyl)amino}propanoate (0.7 g), sodium carbonate (0.3 g) and sodium iodide (0.6 g) in N,N-dimethylacetamide (20 mL) was stirred at 80° C. for 8 hr. The reaction mixture was poured into water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel chromatography (50% ethyl acetate/hexane to 100% ethyl acetate/hexane). To the residue were added ethanol (3 mL), tetrahydrofuran (3 mL) and 1N lithium hydroxide (2.5 mL), and the mixture was stirred at room temperature for 1 hr. The solvent was evaporated under reduced pressure, and water (10 mL) was added. The mixture was neutralized with 1N hydrochloric acid under ice-cooling, and stirred for 1 hr. The resulting precipitate was collected by filtration and dried to give the title compound (527 mg, 54%).
