実験手順

Ethane sulfonylchloride (75.6 mg, 0.588 mmol) was added carefully dropwise to a solution of Example 39H (70.0 mg, 0.147 mmol) and pyridine (93.1 mg, 1.18 mmol) in acetone (7 mL). The reaction mixture was stirred for 4 h and then concentrated in vacuo. The residue was partitioned between ethyl acetate and water. The organic phase was dried (MgSO4), filtered, and concentrated in vacuo. The residue was purified by chromatography on silica gel, eluting with a 0-25% ethyl acetate/hexane gradient to give the title compound (74 mg, 95%). 1H NMR (300 MHz, DMSO-d6) δ ppm 0.42 (m, 1H) 0.69 (d, J=6.62 Hz, 3H) 0.72 (d, J=6.62 Hz, 3H) 0.80 (m, 1H) 1.22 (t, J=7.35 Hz, 3H) 1.33 (m, 1H) 1.57 (s, 3H) 2.07 (m, 1H) 2.22 (m, 1H) 3.19 (m, 2H) 5.76 (s, 1H) 7.53 (dd, J=7.91, 4.23 Hz, 1H) 7.57 (dd, J=8.82, 2.21 Hz, 1H) 7.63 (d, J=2.21 Hz, 1H) 7.71 (d, J=8.82 Hz, 1H) 7.76 (d, J=3.68 Hz, 2H) 8.16 (d, J=7.72 Hz, 1H) 10.31 (s, 1H) 13.77 (s, 1H).).
