Procedure

To a solution of 6-chloro-2-[5-(1,3-dioxo-1,3-dihydro-isoindol-2-ylmethyl)-pyridin-3-yl]-1-methyl-1H-indole-3-carbonitrile (8.96 g, 18.89 mmol) in ethanol (200 mL) is added hydrazine (12.10 mL, 378 mmol) and the reaction mixture is stirred overnight. The mixture is then filtered and the solids are washed with ethyl acetate. The filtrate is partially concentrated to remove ethyl acetate. 1M aqueous HCl is added, and the aqueous mixture is washed with EtOAc. The aqueous layer is then basified with 4M aqueous NaOH and extracted with dichloromethane thrice. The dichloromethane extracts are dried over Na2SO4 and concentrated in vacuo to afford 2-(5-aminomethyl-pyridin-3-yl)-6-chloro-1-methyl-1H-indole-3-carbonitrile as a solid. MS (ESI) m/z 297.0 (M+H)+
