A solution of (5-cyclopropyl-2H-pyrazol-3-yl)-[2-(3-methoxycarbonylphenylsulfanyl)-quinazolin-4-yl]-amine (110 mg, 0.26 mmol) in a mixture of THF/water (1/1, 10 mL) is treated with 1M LiOH (0.75 mL, 0.75 mmol). The mixture is stirred for 20 hours at room temperature and then neutralized with 1M HCl (0.75 mL, 0.75 mmol). A solid forms and is collected by filtration to afford the desired [2-(3-carboxyphenylsulfanyl)-quinazolin-4-yl]-(5-cyclopropyl-2H-pyrazol-3-yl)-amine.
