実験手順

Step E (2): Ba(OH)2.H2O (267 mg, 1.41 mmol) was added to a vial charged with benzyl (2S,3R)-4-((1S,3R)-3-(allyloxy)-6-methoxy-2,3-dihydro-1H-inden-1-ylamino)-1-(3,5-difluorophenyl)-3-hydroxybutan-2-ylcarbamate (diastereomer A, 260 mg, 0.471 mmol) from stepE(1), DME/H2O (3 mL/2 mL). The sealed vial was heated at 110° C. for 18 h. Filtered the reaction mixture through a Pasture pipette/Kimwipe plug to remove solids. Rinsed the vessel and solids with fresh DME. The filtrate was evaporated in vacuo. Residual solvents were removed under high vacuum. The crude residue was purified by silica gel chromatography (1-20% MeOH (containing 0.1% triethylamine)/chloroform linear gradient) to give 74 mg (38% yield) the of the title compound as a clear viscous oil. LC-MS (M+H)+=419.24; 1H NMR (500 MHz, CDCl3) δ 7.32 (d, J=8.24 Hz, 1H), 6.92 (d, J=2.14 Hz, 1H), 6.85 (dd, J=8.24, 2.44 Hz, 1H), 6.71-6.80 (m, 2H), 6.60-6.71 (m, 1H), 5.84-6.03 (m, 1H), 5.30 (dd, J=17.24, 1.68 Hz, 1H), 5.18 (dd, J=10.38, 1.53 Hz, 1H), 4.77 (dd, J=6.10, 3.97 Hz, 1H), 4.08-4.12 (m, 2H), 4.05 (dd, J=6.87, 4.43 Hz, 1H), 3.79 (s, 3H), 3.47-3.52 (m, 1H), 3.04-3.10 (m, 1H), 2.90-3.00 (m, 2H), 2.75 (dd, J=11.90, 8.55 Hz, 1H), 2.61-2.68 (m, 1H), 2.49 (dd, J=13.43, 9.77 Hz, 1H), 1.94-2.00 (m, 1H).
