Reaction Steps
1H-indole-6-carbonitrile (D12) (3.2 g), ferric chloride (3.7 g) and ethyl acrylate (7.3 mL) in DCE (7 mL) was added to a sealed tube. The tube was sealed, and the reaction mixture was stirred at 120° C. for 2 hours. After cooling, the reaction mixture was diluted with DCM. The organic layer was washed with 0.5 M HCl, brine, dried over anhydrous sodium sulfate. The dried solution was concentrated. The residue was purified by column chromatography (20% EtOAc in hexane) to afford ethyl 3-(6-cyano-1H-indol-3-yl)propanoate (D106) (3.1 g) as a yellow solid. δH (CDCl3, 400 MHz): 1.24 (3H, t), 2.71 (2H, t), 3.11 (2H, t), 4.14 (2H, q), 7.24 (1H, dd), 7.36 (1H, dd), 7.67 (1H, d), 7.70 (1H, dd), 8.36 (1H, br s). MS (ES): C14H14N2O2 requires 242. found 243.1 (M+H+).
