Reaction Steps

5-[1-(4-Methoxy-phenyl)-7-oxo-3-trifluoromethyl-1,4,5,7-tetrahydro-pyrazolo[3,4-c]pyridin-6-yl]-pentanenitrile (0.100 g, 0.255 mmol), hydroxylamine hydrochloride (0.027 g, 0.382 mmol), and triethylamine (0.071 mL, 0.510 mmol) were dissolved in ethanol (10 mL). The reaction was refluxed overnight, concentrated, and purified by reverse HPLC and freeze-drying to afford the title compound (0.45 g, 42%): 1H NMR (CHCl3) δ 7.61 (bs, 0.5 H), 7.38 (d, j=8.5 Hz, 2H), 6.94 (d, j=8.8 Hz, 2H), 6.72 (bs, 0.5H), 3.82 (s, 3H), 3.68 (t, j=6.4 Hz, 2H), 3.48 (s, 2H), 3.01 (t, j=6.4 Hz, 2H), 3.35 (s, 3H), 1.56 (bs, 4H) ppm; Mass Spec 426.3(M+H)+.
