Procedure

A mixture of 3-acetyl-5-(1,1-dioxo-1λ6-[1,2]thiazinan-2-yl)-benzoic acid (68.1 mg, 0.23 mmol), HATU (104.6 mg, 0.275 mmol) and Hunig's base (118.5 mg, 0.16 mL, 0.917 mmol) in DMF (1.1 mL) was stirred for 10 min and then tert-butyl 3-methoxybenzyl((2R,3S)-3-amino-4-(3,5-difluorophenyl)-2-hydroxybutyl)carbamate (100 mg, 0.23 mmol) was added. The reaction mixture was stirred at room temperature for 2 h. The reaction mixture was diluted with ethyl acetate, washed with H2O 3 times and concentrated under vacuum to give the title compound (164 mg): 1H NMR (CD3OD, 500 MHz) δ ppm 1.48 (9H, s), 1.93-2.00 (2H, m), 2.32-2.38 (2H, m), 2.64 (3H, s), 2.88 (1H, dd, J=10, 15 Hz), 3.08-3.15 (1H, m), 3.20-3.23 (1H, m), 3.27-3.39 (2H, m), 3.38 (1H, m), 3.74-3.82 (6H, m), 3.96-4.00 (1H, m), 4.20-4.29 (2H, m), 6.76 (1H, m), 6.91-6.92 (3H, m), 7.05-7.08 (2H, m), 7.35 (1H, m), 8.04 (1H, m), 8.07 (1H, m), 8.11 (1H, m). HPLC retention time: 2.112 min (method A). MS (ESI) (M+Na)+ 738.28.
