Procedure
A mixture of methyl 3-[4-({(2E)-3-[5-(4-fluorophenyl)-1-methyl-1H-pyrazol-4-yl]prop-2-enoyl}amino)phenyl]-2-hydroxypropionate (1.34 g), a 2N aqueous sodium hydroxide solution (10 ml) and methanol (20 ml) was stirred at room temperature for 1 hr. The reaction mixture was poured into a 1N aqueous hydrochloric acid solution (100 ml). The precipitated solids were collected by filtration, washed with water and dried to give 3-[4-({(2E)-3-[5-(4-fluorophenyl)-1-methyl-1H-pyrazol-4-yl]prop-2-enoyl}amino)phenyl]-2-hydroxypropionic acid (800 mg, 62%) as colorless crystals.
