Procedure
A solution of methyl N-(2,4-dibenzyloxybenzoyl)glycinate (900 mg) in methanol (20 mL) is treated with 1 M NaOH (20 mL) and stirred at 25° C. for 2 hours. The solution is evaporated, the residue diluted with water, brought to pH 1 and extracted with ethyl acetate. The extract is dried and evaporated. The residue is recrystallized from methanol to yield N-(2,4-dibenzyloxybenzoyl)glycine as a colourless solid (300 mg), m.p. 183° C. H NMR (CDCl3) 4.15(2H,d), 5.05 (2H,s), 5.2(2H,s), 6.6(1H,s), 6.7(1H,d), 7.3-7.5(10H,m), 8.2(1H,d), 8.4(1H,t).
