Reaction Steps

4 M hydrogen chloride in dioxane (1.1 ml, 4.40 mmol) was added to a solution of 3-chloro-5-(1-(tetrahydro-2H-pyran-2-yl)-1H-pyrazol-5-yl)picolinonitrile (1.1 g, 3.81 mmol) in absolute ethanol (15 ml) and stirred at RT for 3 h. Solvents were evaporated and water was added to the residue. The mixture was neutralised with saturated NaHCO3 and extracted with EtOAc. The organic phase was dried over anhydrous Na2SO4, filtered and evaporated to give 0.796 g of the product. 1H-NMR (400 MHz; d6-DMSO): δ 7.10 (d, 1H), 7.92 (d, 1H), 8.58 (d, 1H), 9.17 (d, 1H), 13.4 (bs, 1H).
