Morpholine → 4-(1H-imidazol-1-ylsulfonyl)morpholine

Participants

Reaction Steps

3-(1H-Imidazol-1-ylsulfonyl)-1-methyl-1H-imidazolium trifluoromethanesulfonate (1.5 g, 3.0 mmol) was dissolved in acetonitrile (15 mL) and treated with morpholine (0.30 mL, 4.0 mmol) and stirred for 16 h at ambient temperature. The solvent was removed and the residue subjected to column chromatography (silica gel, heptane, ethyl acetate 1:1, 0:1) to yield 4-(imidazole-1-sulfonyl)-morpholine (0.62 g, 83%) as a white solid; MS: m/e=218.5 (M+H+).
