Potassium Carbonate → 2-nitro-N-({4-[4-(3-pyrrolidin-1-ylpropoxy)phenyl]tetrahydro-2H-Pyran-4-yl}methyl)aniline

{4-[4-(3-Pyrrolidin-1-ylpropoxy)phenyl]tetrahydropyran-4-yl}methylamine (300 mg, 0.94 mmol), 2-fluoronitrobenzene (100 μl, 0.95 mmol) and potassium carbonate (150 mg, 1.08 mmol) were stirred together at room temperature in N,N-dimethylformamide (1 ml) for 2 days. The reaction mixture was concentrated in vacuo and the residue partitioned between water (30 ml) and ethyl acetate (100 ml). The layers were separated and the organic phase washed with water (2×20 ml), dried over sodium sulphate, filtered and concentrated in vacuo to give the title compound as a yellow gum (570 mg, 100%). HRMS ESI+ m/z 440.2537 [MH]+.
