Procedure

A solution of (2-methyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-acetic acid methyl ester ((2.37 g, 11.12 mmol) in dry DMF (38 ml) at room temperature is treated with BEMP (4.39 ml, 15.19 mmol) dropwise. The reaction mixture is stirred at room temperature for 35 minutes and then 1-(1-bromo-ethyl)-4-methanesulfonyl-benzene (4.00 g, 15.18 mmol) and sodium iodide (12.29 g, 15.28 mmol) is added. After stirring at 60° C. for 1 hour, the reaction mixture is allowed to cool to room temperature and then diluted with ethyl acetate/ether (200 ml of a 1:1 mixture) and water (150 ml). The organic portion is washed with brine, dried (Na2SO4) and concentrated in vacuo and the resulting crude is purified by chromatography on silica eluting with ethyl acetate/iso-hexane (2:3 increasing to 1:1 ethyl acetate) to yield the titled product as a racemic mixture. The enantiomers are resolved using a chiralcel OD column eluting with 30% IPA in hexanes to afford enantiomer A (retention time=14.33 minutes) and enantiomer B (retention time=17.68 minutes)
