Procedure

A solution of O-(2-chloroethyl)-N-(4-fluorobenzyl)-hydroxylamine (0.327 g, 1.6 mmol) in acetonitrile (2 ml) was treated with a solution of dimethylamine (16 mmol, 8 ml of a 2 M solution in tetrahydrofuran). Sodium iodide (0.06 g) was then added and the resulting mixture was sealed and heated at 55° C. for 16 h. The cooled mixture was diluted with ethyl acetate, washed with saturated sodium bicarbonate, brine and dried over anhydrous sodium sulphate. Evaporation of the solvent under reduced pressure yielded 0.310 g (91% yield) of the crude title hydroxylamine as a light brown oil which was used as such for the next step. 1HNMR 400 MHz (C6D6) δ (ppm): 2.19 (6H, s, NCH3), 2.47 (2H, t, J=6.1 Hz, CH2), 3.82 (2H, s, NCH2), 3.84 (2H, t, J=6.1 Hz, CH2), 6.9 (2H, m, aromatics), 7.11 (2H, m, aromatics).
