EXAMPLE 17; (2R,3R,4S,5R,6E)-N-[(3R)-6-fluoro-4-oxo-2,3,4,5-tetrahydro-1,5-benzothiazepin-3-yl]-3,4,5-trihydroxy-2-methoxy-8,8-dimethylnon-6-enamide; Step 1: Preparation N-[(2,2-dimethylpropanoyl)oxy]-S-(3-fluoro-2-nitrophenyl)-L-cysteine (48); A solution of <strong>[19064-24-5]2,6-difluoronitrobenzene</strong> 47 (2.0 g, 12.57 mmol) in 26 mL of ethanol is introduced into a 50 mL three-necked flask containing 2.78 g of L-Boc-Cys-OH (12.57 mmol), 22 mL of water and 3.05 g of NaHCO3 (36.33 mmol). The reaction medium is left at room temperature overnight and the medium is then maintained at 75 C. for 1 hour. The ethanol is evaporated off, the aqueous phase is then washed with 20 mL of ether, and once the ether phase has been separated out by settling, the aqueous phase is brought to pH 2-3 with HCl (1N) and extracted twice with 25 mL of EtOAc. The organic phases are combined, dried over MgSO4, filtered and finally evaporated to dryness. 1.29 g of crude product 48 are obtained (yellow oil), which product is used directly in the following step.1H NMR (400 MHz, DMSO-d6), δ (ppm): 1.36 (s, 9H); 3.24 (dd, J=10.0 and 13.5 Hz, 1H); 3.53 (dd, J=5.0 and 13.5 Hz, 1H); 4.08 (m, 1H); 7.20 (d, J=8.0 Hz, 1H); 7.44 (t, J=8.0 Hz, 1H); 7.57 (t, J=8.0 Hz, 1H); 7.69 (dt, J=6.0 and 8.0 Hz, 1H); 12.8 (broad m, 1H).
