To a mixture of [18-(tert-butyl-dimethylsilanyloxy)-4-cyclopropanesulfonylaminocarbonyl-2,15-dioxo-3,16-diaza-tricyclo[14.3.0.04,6]nonadec-7-en-14-yl]-carbamic acid tert-butyl ester (330 mg, 0.48 mmoL) in 25 mL of THF was added tetrabutylammonium fluoride (150 mg, 0.54 mmoL). The reaction mixture was stirred at rt for 18 h, and then the THF was removed by rotary evaporation. The residue was partitioned between ethyl acetate and water. The organic phase was dried (MgSO4) and concentrated in vacuo to give the crude product. It was then purified by triturating with hexane to yield 200 mg (73%) of (4-cyclopropanesulfonylaminocarbonyl-18-hydroxy-2,15-dioxo-3,16-diaza-tricyclo[14.3.0.04,6]nonadec-7-en-14-yl)-carbamic acid tert-butyl ester as a white solid. 1H NMR (500 MHz, CD3Cl) δ 1.87–1.64 (m, 21H), 1.70–1.98 (m, 3H), 2.15–2.56 (m, 5H), 2.85–2.94 (m, 1H), 3.71 (d, J=13.91 Hz, 1H), 4.10–4.26 (m, 2H), 4.51 (t, J=7.87 Hz, 1H), 4.62 (s, 1H), 4.98 (m, 1H), 5.06 (d, J=8.78 Hz, 1H), 5.64–5.71 (m, 1H), 6.72 (s, 1H), 10.24 (s, 1H). LC-MS (Method A, retention time: 2.85 min), MS m/z 569 (M++1).
