Методика

To a slurry of N-{3-[(3-{(3β)-cholest-5-en-3-yl[(2-nitrophenyl)sulfonyl]amino}propyl)amino]-3-oxopropyl}-6-[(2,4-dinitrophenyl)amino]hexanamide (20, 121 mg, 0.124 mmol) and K2CO3 (137 mg, 0.991 mmol) in N,N-dimethylformamide (8 mL) and tetrahydrofuran (4 mL) was added thiophenol (100 μL, 0.971 mmol). After stirring at 23° C. for 18 h, the mixture was filtered and solvent removed in vacuo. Flash column chromatography (MeOH/triethylamine/CH2Cl2, 3:5:100) afforded 3 (50 mg, 51%) mp 157-158° C.; 1H NMR (360 MHz, CDCl3) δ 9.12 (d, J=2.6 Hz, 1H), 8.55 (t, J=5.0 Hz, 1H), 8.26 (dd, J=2.6 Hz, J=9.5 Hz, 1H), 6.91 (d, J=9.6 Hz, 1H), 6.62 (t, J=5.5 Hz, 1H), 5.30 (d, J=4.7 Hz, 1H), 3.51 (dt, J=5.8 Hz, J=5.7 Hz, 2H), 3.41 (dt, J=7.0 Hz, J=5.5 Hz, 2H), 3.33 (dt, J=5.9 Hz, J=5.7 Hz, 2H), 2.74 (t, J=6.0 Hz, 2H), 2.38-2.31 (m, 3H), 2.21-2.14 (m, 3H), 2.01-1.00 (m, 37H), 0.97 (s, 3H), 0.90 (d, J=6.5 Hz, 3H), 0.86 (d, J=1.4 Hz, 3H), 0.84 (d, J=1.4 Hz, 3H), 0.66 (s, 3H); 13C NMR (125.8 MHz, CDCl3) δ 172.6, 171.8, 148.5, 141.6, 136.2, 130.6, 130.5, 124.6, 121.2, 114.1, 58.4, 57.0, 56.3, 50.5, 45.7, 43.5, 42.5, 40.4, 40.0, 39.7, 39.5, 38.2, 37.2, 36.5, 36.4, 36.0, 35.7, 35.5, 32.1 (×2), 29.9, 29.1, 28.6, 28.4, 28.2, 26.7, 25.2, 24.5, 24.0, 23.0, 22.7, 21.2, 19.6, 18.9, 12.0; IR (film) νmax 3354, 3299, 2933, 2868, 1647, 1620, 1335 cm−1; CI m/z 793.5584 (MH+, C45H73N6O6 requires 793.5592).
