Versuchsvorschrift

A stirred solution of ethyl 2-(4-amino-1-methylpiperidin-4-yl)acetate (76 mg, 0.378 mmol) in CH2Cl2 (2 mL) was treated with NEt3 (0.24 mL, 1.70 mmol), and 4-pentylbenzene-1-sulfonyl chloride (140 mg, 0.567 mmol). The reaction was stirred overnight, at room temperature, then the solvent removed in vacuo and the product purified by column chromatography to obtain the title compound (148 mg, 95%). 1H NMR (400 MHz, CD3OD) δ 7.77 (d, 2H, J=7.6 Hz), 7.35 (d, 2H, J=7.3 Hz), 4.00 (q, 2H, J=6.7), 2.69 (t, 2H, J=7.0 Hz), 2.57 (s, 2H), 2.46-2.36 (m, 2H), 2.20-2.02 (m, 7H), 1.68-1.60 (m, 4H), 1.41-1.25 (m, 4H), 1.20 (t, 3H, J=6.4 Hz), 0.89 (t, 3H, J=6.7 Hz); MS ESI 411.3 [M+H]+, calcd for [C21H34N2O4S+H]+ 411.58.
