Reaction Steps
To a stirred solution of 0.058 ml (0.74 mmol) 2-methoxyethanol in 2 ml dioxane at room temperature was added 49 mg (1.24 mmol) sodium hydride (60% dispersion in mineral oil) and stirring continued for 10 minutes. 200 mg (0.49 mmol) 2-chloro-N-(4-methoxy-7-morpholin-4-yl-benzothiazol-2-yl)-isonicotinamide was then added and the mixture heated at 115° C. for 16 h. The reaction mixture was then cooled to room temperature, diluted with ethyl acetate, and washed sequentially with 1 M hydrochloric acid and saturated brine. The organic phase was then dried over sodium sulfate and concentrated in vacuo. Flash chromatography (2/1 ethyl acetate/toluene) afforded 109 mg (50%) 2-(2-methoxy-ethoxy)-N-(4-methoxy-7-morpholin-4-yl-benzothiazol-2-yl)-isonicotinamide as a yellow crystalline solid. ES-MS m/e (%): 467 (M+Na+, 16), 445 (M+H+, 100).
