Reaction Steps

A mixture of 7.0 mmol 2-chloro-4-fluorobenzonitrile (commercial), 10.5 mmol piperazine in 4 ml N,N-dimethylacetamide was heated for 1 h at 85° C. After cooling to RT and evaporation in vacuo, the mixture was diluted with dichloromethane and purified on silica, eluting with a gradient of dichloromethane/MeOH to yield after evaporation the title compound. MS (m/e): 222.1 (MH+, 100%)
