Reaction Steps

To a solution of {2-[5-(1-methyl-2-oxo-1,2,3,4-tetrahydro-quinolin-6-yl)-pyridin-3-yloxy]-ethyl}-carbamic acid tert-butyl ester (example 39, 0.06 g, 0.151 mmol) in MeOH (1 mL) was added 4M HCl in dioxane (0.151 mL, 0.604 mmol) and the reaction mixture was stirred at room temperature over night. The resulting suspension was filtered off and the solid material was triturated in diethyl ether, filtered off and further dried in a high vacuum to give the title compound (0.046 g, 91%) as a white solid. MS: 298.3 (M+H+).
