To a solution of racemic of 2-(5-(5-phenyl-4-(pyridin-2-ylmethylamino)quinazolin-2-yl)pyridin-3-yl) propanenitrile (0.08 g, 0.18 mmol) in ethanol/water (3:3 mL) was added solid NaOH (52 mg, 1.1 mmol). Upon completion of addition, the reaction mixture was heated at 95° C. for 16 h. After this time, the reaction mixture allowed to cool to RT and then water was added (5 mL). Upon completion of addition, 1.0 N HCl was added to the reaction mixture to adjust the pH to 6-7. Once at the prescribed pH, the aqueous portion was extracted with ethyl acetate. The combined organic extracts were dried, filtered and concentrated under reduced pressure to yield racemic 2-(5-(5-phenyl-4-(pyridin-2-ylmethylamino)quinazolin-2-yl)pyridin-3-yl)propanoic acid (32 mg, 39% yield).
