実験手順

Prepared using General Procedure 9: A stirred solution of 4-(3-(tert-butoxy)-2-(4-nitrobenzamido)-3-oxopropyl)-2-methoxyphenyl 4-(heptyloxy)benzoate INT-8 (1.70 g, 2.68 mmol) in THF (30 mL) was degassed under N2 flow. Pd/C (10 wt % 0.17 g, 0.16 mmol) was added and the suspension was degassed under N2 flow. The reaction vessel was flushed with hydrogen gas and the reaction was stirred under an atmosphere of hydrogen overnight. The reaction was diluted with THF (10 mL) and filtered over celite. The material was concentrated and purified by chromatography (EA/hexanes) to afford 1.20 g (73%) of 4-(2-(4-aminobenzamido)-3-(tert-butoxy)-3-oxopropyl)-2-methoxyphenyl 4-(heptyloxy)benzoate INT-9. LCMS-ESI (m/z) calculated for C35H44N2O7: 604; found 605 [M+H]+, tR=3.15 min (Method 4). 1H NMR (400 MHz, DMSO) δ 8.24-8.18 (d, J=7.8 Hz, 1H), 8.05-7.94 (m, 2H), 7.61-7.52 (m, 2H), 7.13-7.04 (m, 4H), 6.93-6.85 (m, 1H), 6.57-6.48 (m, 2H), 5.65 (s, 2H), 4.58-4.50 (m, 1H), 4.12-4.03 (t, J=6.5 Hz, 2H), 3.71 (s, 3H), 3.16-3.03 (m, 2H), 1.79-1.69 (m, 2H), 1.47-1.23 (m, 17H), 0.90-0.82 (m, 3H).
