To a 50 mL RB flask fitted with magnetic stirrer was charged 10 mL of Toluene. to the stirred solvent was added methyl 3-(4-hydroxyphenyl)-3-oxopropanoate (0.2 g, 1.036 mmol) and (4-{[(2Z)-2-(methoxyimino)-2-phenylethyl]oxy}phenyl)methanol (0.22 g, 0.82 mmol) was added Tributyl phosphine (0.271 g, 1.324 mmol) and 1,1′-(Azodicarbonyl)di-Piperidine portion wise at 0° C. (0.339 g, 1.346 mmol). Then the reaction mixture was stirred at RT for 12 h. After completion of the reaction (reaction monitored by TLC), reaction mixture was concentrated and extracted with ethyl acetate. Then the organic layer was dried over anhydrous Na2SO4. Solvent was removed under reduced pressure, and the resulting crude compound was purified by column chromatography on silica gel using petroleum ether and ethyl acetate as eluent (0.05 g Yield: 14%) MS (ESI, 120 eV): m/z=448.1 (M+H)+.
