Reaction Steps
A mixture of N-[({4-[(3-chloro-4-fluorophenyl)oxy]phenyl}amino)carbonyl]-L-alanine (Intermediate 10, 352 mg) in 15 mL of 3N HCl was heated at 100° C. for 16 hours. Then sodium carbonate was added and the mixture was adjusted to pH=8. The mixture was extracted with ethyl acetate (3×50 mL). The combined organic phases were washed with brine and dried with magnesium sulphate. Removal of the solvent afforded crude compound which was purified by column chromatography (MeOH/DCM=1/50) to give 40 mg of the title compound as a white solid.
