Reaction Steps
A mixture of sodium ethoxide (21% w/w, 8.10 mL, 21.8 mmol) and ethyl acetate (0.6 mL) was refluxed for 30 min. Urea (1.30 g, 21.8 mmol) was added and heated till it dissolved completely. 3-{4-[4-(1-Dimethylcarbamoyl-2-pyridin-3-ylethyl)-phenoxy]-phenyl}-propionic acid ethyl ester, 80 (1.74 g, 3.80 mmol) was added and heated for 5 min at 80° C. Reaction mixture was cooled to room temperature, neutralized by trifluoroacetic acid and water (50 mL) was added and extracted with ethyl acetate (3×50 mL). Organic layer was washed with water (2×20 mL) and brine (50 mL). The compound was purified by silica gel chromatography and product was eluted with chloroform-methanol (97:3). Yield: 0.30 g (16.7%).
