실험 절차
Sodium methoxide (108 mg) was added to a solution of E-4-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyimino]-4-phenylbutyric acid (941 mg) in methanol (5 ml), which was stirred at room temperature for 1 hour and concentrated. The remaining crystals were recrystallized from methanol-diethyl ether to obtain sodium E-4-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyimino]-4-phenylbutyrate (456 mg, yield 46%) as colorless crystals. m.p. 64-70° C.
