실험 절차

To a solution of tert-butyl (1R,3S)-3-(2-fluoro-5-(5-fluoro-1-tosyl-1H-pyrrolo-[2,3-b]pyridin-3-yl)phenylamino)cyclohexylcarbamate, 44d, (0.65 g, 1.09 mmol) in methylene chloride (22 mL) was added hydrogen chloride (2.71 mL of 4M solution in 1,4-dioxane, 10.86 mmol). The reaction was heated to 50° C. and stirred for 6 hours. The mixture was cooled to room temperature and concentrated in vacuo, producing a yellow solid. The crude residue was purified via silica gel chromatography (25-50% Ethyl Acetate/hexanes gradient). Desired fractions were combined and concentrated in vacuo to produce 350 mg of 44e as a yellow powder.
