Versuchsvorschrift

To a stirred mixture of compound (I) (1.02 g, 2.9 mmol) and 5-amino-2,3-dimethyl indole (488 mg, 3.04 mmol) in toluene (6.9 mL) that was heated briefly until components partly dissolved and cooled to ambient temperature, was added 2 M solution of trimethylaluminum in toluene (2.32 mL, 1.6 eq) drop-wise under nitrogen purge. Reaction mixture was stirred until bubbling (gas evolution) completed, and then heated at 115° C. (oil bath) for 15 minutes. To a cooled reaction mixture chloroform and 1 N NaOH were added, chloroform layer was separated, washed twice with water, brine and dried over anhydrous sodium sulfate. Flash column chromatography on silica gel (eluent dichloromethane-acetone-methanol (3:1:01)) and recrystallization from chloroform-ethyl acetate mixture afforded target amide, 2-Morpholin-4-yl-6-(2-morpholin-4-yl-ethoxy)-pyrimidine-4-carboxylic acid (2,3-dimethyl-1H-indol-5-yl)-amide, as a pale yellow solid (1.1 g, 79%).
