To a solution of 6 (2-(4-bromo-3-[1,3]dioxolan-2-yl-phenoxy)-6-(2-hydroxy-ethylamino)-nicotinonitrile, 1.1 g, 2.7 mmol) in THF (200 mL) was added a HCl solution (1 M, 100 mL). The reaction was stirred at room temperature overnight. The THF was evaporated in vacuo. The white solid that formed was filtered and air-dried to afford 0.94 g (55% yield for two steps) of the title compound.
