참여 물질

반응 단계

A mixture of 4-[2-(4,5-diphenyl-2-oxazolyl)ethyl]phenol (6.00 g, 17 mmol), methyl bromoacetate (2.96 g, 1.83 mL, 19 mmol), potassium carbonate (2.91 g, 21 mmol), potassium iodide (catalyic amount) and acetonitrile (80 mL) was stirred at reflux. After 1 hour, the mixture was cooled, filtered and the solvent removed to leave a crystalline solid that was tritrated with hexanes and filtered to give methyl 2-[4-[2-(4,5-diphenyl-2-oxazolyl)ethyl]phenoxy]acetate (7.27 g, 100%). An analytical sample was obtained by recrystallizing a 2.25 g batch from methanol to give 1.70 g of pure material which had m.p. 122°-125° C.
