Procedure
To a solution of (2-methyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-acetic acid methyl ester ((0.025 g, 0.122 mmol) in dry DMF (1 ml) under an inert atmosphere of Argon is added dropwise, BEMP (56.6 μl, 0.196 mmol). The mixture is agitated at room temperature for 1 hour before cooling to 0° C. with an ice-bath. A solution of 5-bromomethyl-1-methyl-1H-benzotriazole (0.044 g, 0.196 mmol) in DMF (1 ml) is added to the cooled solution and the resulting mixture is agitated at room temperature for 2 days. The solvent is removed in vacuo and purification of the crude by chromatography on silica eluting with iso-hexane/ethyl acetate (0%-20% ethyl acetate) yields the titled product. (MH+350).
