Potassium Iodide → 4-(4-Morpholinyl)benzenebutanol

Participants

Reaction Steps

A mixture of 4-aminobenzenebutanol (7.5), 2-chloroethyl ether (6.5 g, 5.32 ml), DEA (11.74 g) and finely ground potassium iodide (15.0 g) was stirred in DMF (500 ml) at 100° under nitrogen for 65 h. The mixture was cooled, the solvent removed in vacuo at 55° and the residue partitioned between EA (250 ml) and water (100 ml). The aqueous layer was extracted with further EA (100 ml), the combined organic solutions washed with brine (150 ml), dried and evaporated onto FCC silica (15 g). The impregnated material was applied to an FCC column, elution with ER-CX (2:1) affording the title compound as a waxy cream solid (6.13 g) m.p. 51°-52°.
