Reaction Conditions

Reaction Steps

Ethyl 3-oxo-3-phenyl-2-(pyridin-3-yl)propanoate (1.82 g, 6.76 mmol) was dissolved in hydrogen chloride (8.11 mL, 101.0 mmol) and heated to 100° C. overnight. The reaction was then diluted with H2O (25 mL), extracted with EtOAc (3×50 mL), dried over MgSO4, filtered and concentrated. The residue was purified by silica gel column chromatography to give the title compound as a clear oil (0.894 g). LCMS m/z=198.3 [M+H]+; 1H NMR (400 MHz, CDCl3) δ ppm 4.29 (s, 2H), 7.27 (dd, J=7.07, 5.56 Hz, 1H), 7.49 (t, J=7.58 Hz, 2H), 7.55-7.64 (m, 2H), 7.99-8.05 (m, 2H), 8.49-8.56 (m, 2H).
