Reaction Steps

A mixture of methyl 2-cyano-3-(4-(4-methylpiperazin-1-yl)phenyl)butanoate (700 mg, 2.32 mmol), sodium chloride (405 mg, 6.90 mmol), DMSO (5 ml) and water (2 ml, 3 vol %) and heated at 160-165° C. for 12 h. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with water, brine, dried over anhydrous sodium sulfate, filtered and concentrated in vacuo to afford 450 mg (79.6%) of 3-(4-(4-methylpiperazin-1-yl)phenyl)butanenitrile as a colorless liquid.
