Reaction Steps
4Chloro-3-nitropyridine (160 mg, 1.0 mmol) is added to a stirred solution of 5-(2-aminoethyl)-2-(4-fluorophenyl)hexahydrofuro[2,3-b]furan (200 mg, 0.8 mmol) and triethylamine (1.0 ml) in chloroform (15 ml) at ambient temperature. The reaction mixture is stirred overnight, then washed with water, dried over anhydrous magnesium sulphate, filtered and the solvent removed under reduced pressure to leave an orange oil. This is purified by chromatography over silica (1:1 ethyl acetate/hexane) to give 2-(4-fluorophenyl)-5-(2-(N-3-nitropyrid-4-ylaminoethyl)hexahydrofuro[2,3-b]furan (175 mg, 59%) as a yellow amorphous solid.
