实验步骤: To a solution of 4-(diethylamino)piperidine dihydrochloride (3.0 g, 0.019 mmol) in water (20 mL), 2M sodium hydroxide solution (5.0 mL) was added at ambient temperature. The mixture was stirred for 30 min. The solvent was removed under reduced pressure, and methanol (10 mL) was added to the crude material, then the residue was removed by filtration. The filtrate was concentrated and dried to afford 4-(diethylamino)piperidine (1.7 g, y. 77%) as solid. The solvent was removed under reduced pressure, and methanol (10 mL) was added to the crude material the residue was removed by filtration The filtrate was concentrated dried

实验步骤: 2-(7-Bromo-4-quinolylamino)benzoic acid is converted to the acid chloride which is reacted with 4-diethylamino piperidine as in Example 1 to give the title compound.

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: The title compound is synthesized by coupling of Diethyl-piperidin-4-yl-amine (commercially available from CHESS GmbH) and bromoacetonitrile analogously to the preparation of Intermediate 149.2 as a colorless oil; ES-MS: M+=196.2: 1HNMR(DMSO-d6) 3.65 (s, 2H), 2.80-2.75 (m, 2H), 2.45-2.30 (m, 5H), 2.15-2.05 (m, 2H), 1.70-1.60 (m, 2H), 1.45-1.35 (m, 2H), 0.95 (t, 6H). analogously to the preparation of Intermediate 149.2 as a colorless oil
