Procedure

To a clear solution of mixture of 9 and 10 (6-[2-(tert-butyl-dimethyl-silanyloxy)-ethylamino]-2-[3-formyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenoxy]-nicotinonitrile and 6-[2-(tert-butyl-dimethyl-silanyloxy)-ethylamino]-2-(3-formyl-phenoxy)-nicotinonitrile) in MeOH (anhydrous, 200 mL) was slowly added NaBH4 (0.26 g, 6.9 mmol). The reaction was stirred at room temperature for 4 hours, before the addition of HCl solution (1 M, 30 mL). After overnight at room temperature, the solution was slowly evaporated in vacuo. Purification was accomplished by reverse phase Biotage with 5%-100% MeOH/H2O gradient to afford 120 mg (29% yield) of the title compound as a white solid.
