実験手順

A mixture of N-[3-ethoxycarbonyl-phenyl]-4-(2-chloro-3-pyridyl)-2-pyrimidineamine (1.15 g, 3.24 mmol), sodium hydroxide (300 mg, 7.5 mmol) in acetonitrile (15 mL) and water (5 mL) is heated to reflux for 4 hours. The reaction mixture is then cooled to room temperature and concentrated. The residue is dissolved in water and acidified with 10% hydrochloric acid. The solid is collected by filtration and washed with water, methanol and dried to give N-[3-carboxy-phenyl]-4-(2-chloro-3-pyridyl)-2-pyrimidineamine (600 mg); ESI-MS (m/z): 327.0 (M++H).
