실험 절차

A mixture of N-[3-ethoxycarbonyl-phenyl]-4-(2-chloro-4-pyridyl)-2-pyrimidineamine (860 mg, 2.43 mmol), lithium hydroxide (233 mg, 9.70 mmol) in ethanol (20 mL) and water (5 mL) is heated to reflux for 1 hour before cooling to room temperature. The mixture is concentrated, 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-4-pyridyl)-2-pyrimidineamine (760 mg); ESI-MS (m/z): 327.0 (M++H).
