실험 절차

189 mg of crude Dimethyl-[3-(1H-pyrrolo[2,3-b]pyridin-5-yl)-prop-2-ynyl]-amine was stirred in 5 ml of DCM with AlCl3 (4 equivalents) for 30 minutes. Two equivalents of (2,3-Difluoro-phenyl)-acetyl chloride were added and the reaction was stirred in a sealed tube overnight. The LC/MS showed the reaction to be complete and was worked-up under standard conditions. Normal phase column chromatography yielded 101 mg of 2-(2,3-Difluoro-phenyl)-1-[5-(3-dimethylamino-prop-1-ynyl)-1H-pyrrolo[2,3-b]pyridin-3-yl]-ethanone with a yield over two steps of 33%. LC/MS retention time of 1.83 minutes. M+ 354.17, M− 352.1
