Reaction Steps

To a solution of sulfamide (1.0 g, 10.4 mmol) in dry DMF (50 mL) is added NaH (416 mg 60% dispersion in mineral oil, 10.4 mmol) in portions. After the evolution of gas has stopped, (3-bromo-propoxymethyl)-benzene (2.38 g, 10.4 mmol) is added and the reaction mixture is stirred at 50° C. for 18 h. The suspension is cooled to rt, neutralized with 1N aq. HCl (5 mL) and concentrated. The solid residue is suspended in acetone and filtered. The filtrate is evaporated and the residue is purified by column chromatography on silica gel eluting with hexane/EA to afford 3-benzyloxypropylsulfamide (651 mg) as a colourless oil. LC-MS: tR=0.73 min, [M+H]+=245.18; 1H NMR (CDCl3): δ 7.39-7.27 (m, 5H), 4.94 (t br, J=4.6 Hz, 1H), 4.53 (s br, 2H), 4.50 (s, 2H), 3.60 (t, J=5.9 Hz, 2H), 3.26 (q, J=5.9 Hz, 2H), 1.89 (p, J=5.9 Hz, 2H).
