A suspension of 1-O-acetyl-2,3,5-tri-O-benzoyl β-D-ribofuranose (1 g, 2.0 mmol), p-hydroxybenzaldehyde (0.5 g, 4.1 mmol), and boron trifluoride diethyletherate (0.12 ml, 1 mmol) in 20 ml of dry dichloromethane was stirred overnight at room temperature. The solvent was removed in vacuo and the residue extracted with ethyl acetate and brine. The organic layer was dried with sodium sulfate, filtered and the solvents were removed in vacuo. The residue was not purified further, but suspended in methanol and the pH adjusted to 11 with 1.0 N aqueous NaOH. This was stirred and with occasional readjustment of the pH until t.l.c. on silica gel (eluant 1:1 ethyl acetate/hexanes) indicated only material at the solvent front or baseline. Silica gel was added directly to the reaction material and the solvent removed in vacuo. The powder was added to a column of silica gel and purified by flash chromatography with 100% ethyl acetate as eluant. The title compound was obtained as a colourless syrup.

Procedure:
A solution of ethyl 2-((benzyl(cyclopentyl)amino)methyl)-2-fluorobutanoate (2.2 g, 6.8 mmol) in ethanol (20 mL) was hydrogenated with Pd(OH)2 (20%, 240 mg, 0.34 mmol) in presence of TFA (6.8 mmol) at atmospheric pressure for 20 h. The reaction mixture was filtered through celite. The filtrate was concentrated and diluted to EtOAc/H2O, aqueous layer was basified to pH=11-12 by 1N NaOH. The organic layer was then dried and concentrated to give the product (1.38 g, 88%) as light yellow liquid. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 0.95 (t, J=7.6 Hz, 3H) 1.31 (t, J=7.1 Hz, 4H) 1.41-1.94 (m, 9H) 2.88-3.08 (m, 3H) 4.26 (qd, J=7.12, 2.40 Hz, 2H).

Procedure:
N′-[4-(tert-Butyl-dimethyl-silanyloxy)-cyclohexylidene]-hydrazinecarboxylic acid tert-butyl ester (4.103 g, 11.98 mmol) was dissolved in dry tetrahydrofuran (11.5 mL) and dry methanol (15.0 mL). Sodium cyanoborohydride (0.945 g, 14.29 mmol) was added portionwise. When the effervescence subsided the mixture was refluxed for 1.5 hours. At this time a small additional amount of sodium cyanoborohydride (0.047 g, 0.75 mmol) was added and refluxing was continued for another 30 minutes to insure complete reaction. After cooling to room temperature, 6N HCl (10 mL) was added, resulting in precipitation of a white solid. The mixture was heated at 70° C. for 6 hours and then cooled to room temperature and stirred for 12 hours. The reaction mixture was concentrated and azeotroped with toluene to remove nearly all of the water. The residue was then dissolved in hot isopropanol and cooled back down to room temperature. Any insoluble material was removed by filtration. The filtrate was diluted with ether and chilled. The material dropped out of solution as an oil/gum. The mother liquor was removed by decantation. The oil/gum was then washed with ether and dried in vacuo to give 4-hydrazino-cyclohexanol hydrochloride (1.920 g, 96%). A second crop (0.261 g, 13%) was collected from the mother liquor. The yield was greater than theoretical due to the presence of trapped solvent and small impurities. The material was used without any further purification.

Procedure:
Pyridine (551 mg, 5.8 mmol) and acetic anhydride (650 mg, 0.6 mL, 6.4 mmol) were added to a cold solution (at 0° C.) of 4-bromo-phenylamine (1 g, 5.8 mmol) in DCM (10 mL) and stirring was continued at ambient temperature for 2 hrs. The reaction mixture was diluted with DCM and washed the organic layer with water followed by brine solution. The organic layer collected was dried over sodium sulfate and concentrated under reduced pressure to afford 900 mg (69.5% yield) of N-(4-bromo-phenyl)-acetamide.

Procedure:
To a solution of cyclopropane-1,1-dicarboxylic acid [4-(7-benzyloxy-6-methoxy-quinolin-4-yloxy)-3-fluoro-phenyl]-amide (4-fluoro-phenyl)-amide (1.18 g, 2.0 mmol) in EtOH (20 mL) was added 1,4-cyclohexadiene (2.0 mL, 20 mmol) and 10% Pd/C (300 mg). The reaction mixture was then heated to reflux and the stirring was continued for 2 h. It was cooled to room temperature, filtered through celite and washed with MeOH. The MeOH solution was then concentrated under reduced pressure. The residue was taken into EtOAc (200 mL). The EtOAc solution was washed with water, and dried over Na2SO4. Removal of the solvent under reduced pressure gave 900 mg (89%) of the crude product (90% purity by analytical HPLC), which was used in the next reaction without further purification.
