実験手順

The 4-butoxylphenyl sulfonyl chloride (160 μmol, 2.0 eq, 400 μL of a 0.40 M in anhydrous pyridine) and tert-butyl (6-aminopyridin-2-yl)carbamate (80 μmol, 1.0 eq, 400 μL of a 0.20 M in anhydrous pyridine) was added into a test tube (75×10 mm, dried by heating at 110° C. for 16 h before use) equipped with a stir bar. The test tube was covered with Parafilm, and was stirred for 24 h at ambient temperature. The solvent (pyridine) was evaporated in vacuo. Trifluoroacetic acid (320 μL, 52.0 eq., excess, neat) was added into the test tube. The test tube was capped and vortexed for 5 h at ambient temperature. The excess TFA was removed in vacuo, and the residue was dissolved in DMSO (1.340 mL) and purified by HPLC. 1H NMR (500 MHz, DMSO-d6) δ: 7.73 (d, J=7.7 Hz, 2H), 7.21 (t, J=7.2 Hz, 1H), 6.96 (d, J=6.9 Hz, 1H), 6.10 (d, J=6.1 Hz, 1H), 5.92 (d, J=5.9 Hz, 1H), 3.96 (t, J=6.6 Hz, 1H)), 1.64 (m, 2H), 1.37 (m, 2H), 0.87 (t, J=7.4 Hz, 3H). LRMS m/z: 322.0.
