Reaction Steps

To a solution of ethyl 5-(5-phenyl-4-(pyridin-2-ylmethylamino)quinazolin-2-yl)nicotinonitrile (described in Example 6, 0.10 g, 0.24 mmol) in ethanol (5 mL) was added hydroxylamine hydrochloride (0.033 g, 0.48 mmol) and potassium carbonate (0.076 g, 0.72 mmol). The reaction mixture was heated to reflux at 80° C. for 16 h. The ethanol solvent was evaporated under reduced pressure and the residue was dissolved in DCM, and washed with water. The organic layer was dried, filtered and concentrated to provide N-hydroxy-5-(5-phenyl-4-(pyridin-2-ylmethylamino)quinazolin-2-yl)nicotinimidamide (0.2 g) which was used without further purification. LCMS Method X: retention time 1.788 min; [M+1]=448.0.
