Reaction Steps

To 0.5 mmol 1,2-difluoro-4-(3,3,3-trifluoro-propane-1-sulfonyl)-benzene in 5 ml N,N-dimethylacetamide was added 1.5 mmol piperazine, and the mixture was heated at 80° C. for 90 min. The mixture was then concentrated in vacuo, and the residue was chromatographed on silica gel (eluant: methanol/dichloromethane gradient) to afford the title compound. MS (m/e): 341.2 (M+H+, 100%)
