Versuchsvorschrift
Lithium hydroxide monohydrate (44.6 mg) was added to a solution of E-4-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyimino]-4-phenylbutyric acid (500 mg) in methanol (10 ml), which was stirred at room temperature for 30 minutes and concentrated. The remaining crystals were recrystallized from methanol-diethyl ether to obtain lithium E-4-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxyimino]-4-phenylbutyrate (485 mg, yield 96%) as colorless crystals. m.p. 201-203° C.
