Reaktionsschritte

1-(Phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridine-3-carbaldehyde (0.25 g, 0.87 mmol) was dissolved in dry THF (9 mL) and chilled to 0° C. Cyclopropylmagnesium chloride (2.6 mL of a 0.5M solution in THF, 1.5 eq.) was then added by syringe to the cold reaction mixture and stirred at 0° C. for 30 minutes. The mixture was then quenched with saturated ammonium chloride solution, extracted with EtOAc, extracts dried over sodium sulfate and concentrated to provide cyclopropyl(1-(phenylsulfonyl)-1H-pyrrolo[2,3-b]pyridin-3-yl)methanol (0.285 g, 98%). m/z (APCI-pos) M+1=329.1.
