Procedimiento

Benzenesulfonyl chloride (92a) (0.88 g, 5.0 mmol) was added to the mixture of methyl 6-aminohexanoate hydrochloride (91) (1.82 g, 10 mmol) in acetonitrile (10 ml) and sodium carbonate (2.6 g, 24.6 mmol) in water (10 ml). The mixture was stirred for 6 hours at ambient temperature, and the product was extracted with ethyl acetate (30 ml). The extract was dried (Na2SO4) and solvents were removed under reduced pressure. The product was chromatographed on silica gel with ethyl acetate-hexane (1:2) as eluent. The title compound was obtained as oil (1.28 g, 90%). 1H NMR δH (90 MHz, DMSO-d6) δ: 0.90–1.63 (6H, m, CH2); 2.21 (2H, t, J=7.0 Hz, CH2); 2.71 (2H, q, J=6.0 Hz, CH2N); 3.58 (3H, s, CH3); 7.40–7.72 (3H, m, C6H3); 7.72–7.89 (2H, m, C6H2).
