Reaction Steps

A stirred mixture of 2-chloro-5-nitro-6-[(phenylsulfonyl)methyl]pyridine (1.41 g, 4.50 mmol), 1-benzylpiperazine (0.873 g, 4.95 mmol), and K2CO3 (0.683 g, 4.95 mmol) in ethanol is heated at reflux temperature for 1.5 h, cooled, diluted with water and extracted with CH2Cl2. The extracts are combined, dried over MgSO4 and concentrated in vacuo. The resultant residue is chromatographed (silica gel, EtOAc as eluent) to afford the title compound as an orange-yellow solid, 1.96 g (96% yield), mp 175-176° C., identified by NMR and mass spectral analyses.
