Procedure

A mixture of (2E)-3-{3-[(4-{[2-(2-furyl)-5-methyl-4-oxazolyl]methoxy}-3-methoxybenzyl)oxy]-1-phenyl-1H-pyrazol-4-yl}-2-propenoic acid (0.40 g), 1-hydroxybenzotriazole monohydrate (0.17 g), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.22 g), morpholine (0.10 g) and N,N-dimethylformamide (10 mL) was stirred at room temperature for 15 hrs. Water was poured into the reaction mixture, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated to give 4-((2E)-3-{3-[(4-{[2-(2-furyl)-5-methyl-1,3-oxazol-4-yl]methoxy}-3-methoxybenzyl)oxy]-1-phenyl-1H-pyrazol-4-yl}-2-propenoyl)morpholine as yellow crystals (0.41 g, yield 91%). Recrystallization from ethyl acetate-hexane gave yellow prism crystals. melting point: 180-181° C.
