Procedure

BEMP (182 μL, 0.63 mmol) is added to a stirring solution of (2-methyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-acetic acid methyl ester prepared as described in U.S. Pat. No. 3,320,268 (80 mg, 0.39 mmol) in DMF (2.4 mL). After 30 minutes, benzyl bromide (75 μL, 0.63 mmol) is added and the reaction stirred for 3 days, before partitioning between water and 1:1 EtOAc/ether. The organic layer is washed with brine then reduced in vacuo. The residue is purified by flash column chromatography (3:1 iso-hexane/EtOAc elution) to furnish (1-benzyl-2-methyl-1H-pyrrolo[2,3-b]pyridin-3-yl)acetic acid methyl ester; MH+=295.
