    • Preparation of the Fluoride 6 A mixture of the bromide 3 11 (15 g, 42 mmol) and AgF (53 g, 0.42 mol) in dry MeCN (0.25 L) was stirred at 25°C for 22 h, before it was filtered through silica. The filtrate was concentrated under reduced pressure and the residue was chromatographed on silica, eluting with Et2O-hexane (1:1, v/v, to give the fluoride 6 (3.7 g, 30, as a colorless oil. 1H NMR (CDCl3, δ, 1.36 (3 H, d, J, 25 Hz, 1.43 (3 H, d, J, 25 Hz, 2.62 (2 H, m, 3.73 (3 H, s, 5.15 (1 H, m, 7.72-7.79 (4 H, m, 13C NMR (CDCl3, δ, 170.1 (s, 167.9 (s, 134.5 (s, 132.2 (s, 123.9 (s, 94.8 (d, J, 167 Hz, 53.4 (s, 48.6 (s, 38.9 (d, J, 21 Hz, 28.3 (d, J, 24 Hz, 25.8 (d, J, 25 Hz, Preparation of the Hydrazide 7 A mixture of the fluoride 6 (2 g, 6.8 mmol)and N2H4·-H2O (2.9 mL, 59 mmol) in EtOH 30 mL
