Versuchsvorschrift

4-methylpiperidine (180 mg, 1.813 mmol) was added to the 3-(chlorosulfonyl)benzoic acid (200 mg, 0.906 mmol) in presence of Potassiumcarbonate (251 mg, 1.813 mmol) in THF (Volume: 5 ml) at room temperature and the reaction mixture was stirred for 12 h at room temperature. Reaction was monitored by TLC. After completion of the reaction, the solvent was removed by vacuum and then compound was purified by column chromatography (3% CH3OH/CH2Cl2) afforded the title compound as a solid. 1H NMR (CD3OD, 400 MHz): δ 8.32 (m, 1H), 8.27 (m, 1H), 7.96 (m, 1H), 7.72 (t, 1H, J=8.0 Hz), 3.72 (m, 2H), 2.27 (m, 2H), 1.68 (m, 2H), 1.29 (m, 1H), 1.21 (m, 2H), 0.88 (d, 3H, J=6.4 Hz).
