実験手順

To a solution of 6-(6-{1-[2-(tetrahydro-pyran-2-yloxy)-ethyl]-1H-pyrazol-4-yl}-[1,2,3]triazolo[4,5-b]pyrazin-1-ylmethyl)-quinoline (780 mg, 1.71 mmol) in CH2Cl2 (20 mL) was added the anhydrous HCl dioxane solution dropwise (4N, 1.07 mL, 4.27 mmol). A white solid was precipitated out. The reaction mixture was stirred for 1 hour and the LCMS showed the completion of the reaction. The reaction mixture was concentrated, and the residue was dissolved in distilled water (15 mL). The solution was adjusted to pH 7 with Na2CO3. An off-white solid was crashed out, which was filtered, washed with water, and dried on a high vacuum for 1 hour. The solid was re-crystallized from EtOH (50 mL) to provide 2-[4-(3-Quinolin-6-ylmethyl-3H-[1,2,3]triazolo[4,5-b]pyrazin-5-yl)-pyrazol-1-yl]-ethanol (400, 63% yield) as a white crystalline solid with a melting point of 222° C. 1H NMR (400 MHz, DMSO-d6) δ 9.22 (s, 1H) 8.89 (dd, J=4.14, 1.70 Hz, 1H) 8.63 (s, 1H) 8.37 (dd, J=8.38, 1.04 Hz, 1H) 8.32 (s, 1H) 7.98-8.04 (m, 2H) 7.82 (dd, J=8.67, 2.07 Hz, 1H) 7.53 (dd, J=8.29, 4.14 Hz, 1H) 6.15 (s, 2H) 4.96 (t, J=5.27 Hz, 1H) 4.24 (t, J=5.46 Hz, 2H) 3.78 (q, J=5.46 Hz, 2H).
