Synthesis

An activated carbon-supported platinum catalyst (Pt / C, 0.06 mg platinum, 0.0003 mmol, 0.1 mol percent) was added to a 10 mL Schlenk tube; after the evacuation of argon, add 1 mL of solvent (toluene). Under argon protection, to the above system, Were successively added phenylsilane (78.9 mg, 0.75 mmol), 3-Anilinopropionitrile (43.9 mg, 0.3 mmol) and formic acid (27.6 mg, 0.6 mmol). The whole anti-reaction was carried out at 80 ° C with stirring for 15 hours. After completion of the reaction, 3 mL of ethyl acetate was added to the system. The reaction was quenched with aqueous sodium hydroxide (3 mol / L, 3 mL). Ethyl acetate (3 x 10 mL), the organic phase was separated, Dried over anhydrous Na2SO4, and filtered; the solvent was removed by rotary evaporation. The residue was purified by column chromatography on ethyl acetate/petroleum ether = 1: 50 mixed solvent. Separation and purification gave N-(2-Cyanoethyl)-N-methyl aniline 226.4 mg, yield of 55 per cent.
