Procedure

Morpholin-4-ylamine (0.1 mL, 1.16 mmol) and tetrabutylammonium iodide (0.075 g, 0.2 mmol) were sequentially added with stirring to a solution of the carboxylic acid of Example 56k (0.250 g, 0.59 mmol) in dry DMF (4 mL). The reaction mixture was then stirred at 120° C. for 5.5 h in an atmosphere of nitrogen. It was treated with cold water and the solid that precipitated was filtered, washed with water, and dried. The solid was treated with a methanolic HCl solution and refluxed at 70° C. for 3 h. The solution was concentrated and treated with an aqueous sodium bicarbonate solution. The solid that precipitated was filtered, washed with water, dried and purified using flash chromatography (silica gel, 2% methanol/chloroform) to obtain the title compound. Yield: 0.105 g, (36.45%). 1H NMR (DMSO-d6): δ 2.50-2.60 (m, 4H, 2CH2), 2.70 (s, 3H, CH3), 2.80 (t, 2H, CH2), 2.80 (t, 2H, CH2), 3.62-3.70 (m, 4H, 2CH2), 3.90 (s, 3H, OCH3), 5.20 (s, 2H, CH2), 6.20 (t, 1H, NH), 6.85 (s, 2H, 2Ar), 8.15 (s, 1H, Ar), 8.25 (s, 1H, Ar); MS: m/e (CI+) 496 (M+).
