Procedure
A mixture of 34 g (75 mmol) of ethyl (2R)-2-[2-[(7-bromo-5-fluoro-quinazolin-4-yl)amino]-5-fluoro-phenoxy]propanoate and 225.5 ml 1 mol/l aq. NaOH solution in THF are stirred for 2 h at RT. The solvent is evaporated and water is added. The mixture is neutralized with 1 mol/l aq. HCl and the precipitate is filtered off and dried yielding (2R)-2-[2-[(7-bromo-5-fluoro-quinazolin-4-yl)amino]-5-fluoro-phenoxy]propanoic acid.
