Procedure

Step E (1): A mixture of benzyl (S)-2-(3,5-difluorophenyl)-1-((S)-oxiran-2-yl)ethylcarbamate (1.0 g, 3.0 mmol), cis-3-(allyloxy)-6-methoxy-2,3-dihydro-1H-inden-1-amine (657 mg, 3.0 mmol) and LiClO4 (1.60 g, 15 mmol) in CH3CN (10 mL) with was stirred at 30° C. for 2.5 days. The resulting mixture was poured into brine/NaHCO3 solution and extracted with EtOAc. The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by silica gel chromatography (1-20% MeOH (containing 0.1% triethylamine)/chloroform linear gradient) to give two pure diastereomers 265 mg (16% yield) of 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, first to elute) and 270 mg (16% yield)of benzyl (2S,3R)-4-((1R,3S)-3-(allyloxy)-6-methoxy-2,3-dihydro-1H-inden-1-ylamino)-1-(3,5-difluorophenyl)-3-hydroxybutan-2-ylcarbamate (diastereomer B, second to elute). Data for diastereomer A: HRMS (M+H)+=553.2534; 1H NMR (500 MHz, DMSO-d6) δ 7.21-7.35 (m, 4H), 7.14-7.21 (m, 2 H), 7.03 (t, J=9.46 Hz, 1H), 6.87-6.99 (m, 3H), 6.83 (dd, J=8.24, 2.14 Hz, 1H), 5.88-6.00 (m, 1H), 5.30 (dd, J=17.09, 1.83 Hz, 1H), 5.14 (dd, J=10.53, 1.98 Hz, 1H), 4.96-5.02 (m, 1H), 4.83-4.95 (m, 2H), 4.75 (t, J=6.41 Hz, 1H), 4.01-4.13 (m, 2H), 3.91-4.00 (m, 1H), 3.72-3.76 (m, 3H), 3.64-3.72 (m, 1H), 3.44-3.53 (m, 1H), 3.06 (dd, J=13.73, 3.05 Hz, 1H), 2.65-2.75 (m, 1H), 2.54-2.65 (m, 2H), 1.92-2.02 (m, 1H), 1.57-1.67 (m, 1H). Data for diastereomer B: HRMS (M+H)+=553.2509; 1H NMR (500 MHz, DMSO-d6) δ 7.20-7.37 (m, 4H), 7.12-7.22 (m, 2H), 6.98-7.13 (m, 1H), 6.86-7.00 (m, 3H), 6.82 (dd, J=8.24, 2.14 Hz, 1H), 5.80-6.05 (m, 1H), 5.30 (dd, J=17.40, 1.83 Hz, 1H), 5.14 (d, J=10.38 Hz, 1H), 4.80-5.03 (m, 3H), 4.74 (t, J=5.95 Hz, 1H), 3.99-4.15 (m, 2H), 3.95 (t, J=6.10 Hz, 1H), 3.62-3.77 (m, 3H), 3.49 (d, J=4.88 Hz, 1H), 3.03 (dd, J=13.89, 3.20 Hz, 1H), 2.54-2.80 (m, 4H), 2.01-2.18 (m, 1H), 1.59-1.76 (m, 1H).
