Step 1: Preparation of3-Dimethylaminomethyl-pyrrolo[2,3-b]pyridine-l-carboxylic acid tert- butyl ester (511); [0112] To dimethyl-(lH-pyrrolo[2,3-b]pyridin-3-ylmethyl)-amine (2, 2.50 g, 14.3 mmol.) in tetrahydrofuran (200.0 mL) was added sodium hydride (0.685 g, 60% in mineral oil, 17.1 mmol). After 10 minutes, di-te^-butyldicarbonate (3.74 g, 17.1 mmol) was added to the reaction. The reaction was stirred al room temperature overnight. The reaction was poured into water and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 30% ethyl acetate in hexane to give as a white solid (511, 3.80 g, 96.7%).
