Procedure

To a solution of 2-(4-bromo-3-[1,3]dioxolan-2-yl-phenoxy)-6-[(2-hydroxy-ethyl)-methyl-amino]-nicotinonitrile (8) (400 mg, 0.95 mmol) in THF (30 mL) was added HCl solution (1 M, 10 mL). The reaction was stirred at room temperature overnight. After the reaction, all THF was evaporated under vacuum. The aqueous solution was extracted with EtOAc (2×50 mL). The organic layer was washed with water (3×50 mL). The organic layer was dried over MgSO4, filtered and evaporated under vacuum to afford the desired product 320 mg (89% yield) that was used without further purification. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 10.35 (s, 1 H), 7.91 (d, J=2.7 Hz, 1 H), 7.67 (t, J=9.2 Hz, 2 H), 7.32 (dd, J=8.6, 2.7 Hz, 1 H), 6.24 (d, J=8.6 Hz, 1 H), 3.70-3.62 (m, 2 H), 3.56-3.49 (m, 2 H), 3.04 (s, 3 H).
