実験手順

To a solution of 60 mg (0.15 mmol) of 3-benzyloxycarbonylamino-3-methyl-N-[2,3,4,5-tetrahydro-2-oxo-1H-1-benzazepin-3(R)-yl]butanamide (Step D) in 0.5 mL of dry dimethylformamide under nitrogen was added 6.4 mg (0.16 mmol) of 60% sodium hydride/oil dispersion. After stirring for 15 minutes, a solution of 60 mg (0.15 mmol) of 2'-[(t-butoxycarbonylamino)methyl]-1,1'-biphenyl-4-methanol, methanesulfonate ester (Step I) in 0.5 mL of dimethylformamide was aded by cannula. The flask which originally contained the methanesulfonate ester was rinsed with 0.5 mL of dimethylformamide which was added to the reaction mixture. After stirring at room temperature for two hours, the reaction mixture was diluted with 75 mL of ethyl acetate, washed with 20 mL of water and 20 mL of saturated aqueous sodium chloride. The organic layer was dried over magnesium sulfate, filtered and the solvent removed under vacuum. The residue was purified by flash chromatography on silica gel eluting with ethyl acetate/hexane (60:40) to afford 89 mg (96%) of the product as a white foam. FAB-MS: calculated for C42H48N4O6 704; found 705 (M+H). 1H NMR (200 MHz, CDCl3); 1.31 (s, 3H), 1.32 (s, 3H), 1.37 (s, 9H), 1.76 (s, 1H), 2.30-2.62 (m, 5H), 4.15 (d, 5 Hz, 2H), 4.40-4.60 (m, 2H), 4.85 (d, 14 Hz, 1H), 4.95 (d, 10 Hz, 1H), 5.04 (d, 10 Hz, 1H), 5.18 (d, 14 Hz, 1H), 5.65 (s, 1H), 6.70 (d, 6 Hz, 1H), 7.10-7.42 (m, 17H).
