To a cooled solution at 0° C. of methyl 1H-pyrrolo[2,3-b]pyridin-3-ylacetate (1.1 g, 5.8 mmol) in DMF (12 mL) was added 60% NaH in oil (0.26 g, 6.4 mmol, 1.1 equiv.). After a period of 10 min at room temperature, the reaction mixture was cooled to 0° C. and a DMF solution (12 mL) of (2R)-2-(2-{[tert-butyl(dimethyl)silyl]oxy}ethyl)-1-[(4-fluorophenyl)-sulfonyl]aziridine (2.0 g, 5.8 mmol) was added. The reaction was aged 0.5 h at room temperature and poured over saturated ammonium chloride and ethyl acetate. The organic phase was separated, dried over sodium sulfate, filtered and evaporated under reduced pressure. The residue was purified by combiflash (hexane to 50% ethyl acetate in hexane) to provide 1.2 g of the title compound.
