Procedure:
To a solution of 3-chloro-6-(phenylethynyl)pyridazine (CAS 77778-15-5) (180 mg, 839 μmol) and 4,4-dimethylpyrrolidin-2-one (CAS 66899-02-3) (142 mg, 1.26 mmol, 1.5 equiv.) in 2 ml of DMF were added cesium carbonate (546 mg, 1.68 mmol, 2 equiv.). The suspension was heated 16 hours at 120° C. and then allowed to cool to room temperature. Ethyl acetate (10 ml) were added and the unsoluble salts were filtered off. After concentration in vaccuo, the residue was dissolved in 10 ml of ethyl acetate. Silicagel (4 g) were added and the suspension was evaporated to dryness. The silicagel with the adsorbed crude mixture was loaded onto a 20 g silicagel flash chromatography column and eluted three min. with heptane followed by a heptane to 45% ethyl acetate/heptane gradient over 25 min to yield 36 mg (15% yield) of the title compound as a cristalline yellow solid, MS: m/e=292.3 (M+H+).

Procedure:
Compound 20a (39.96 g, 165.7 mmol) was dissolved in dioxane (25 mL) and the solution added dropwise with stirring to 4 N HCl in dioxane (Aldrich, 250 mL). After 45 min, TLC analysis indicated complete deprotection. Volatiles were removed under reduced pressure, and the residue co-evaporated twice with MeOH (2×100 mL). Ether (300 mL) and MeOH (10 mL) were added to the brown, oily residue and the mixture stirred overnight at room temperature resulting in the precipitation of a semi-solid. Additional MeOH (15 mL) was added and stirring continued for 6 h, at which point a yellowish solid was collected by filtration. The product was washed with 5% MeOH in ether (50 mL) and ether (2×50 mL), and dried in vacuo to give compound 20b as a yellowish solid (22.60 g, 76% yield). Filtrates (including washings) were evaporated in vacuum to give additional 20b as a brown oil (7.82 g, 26% yield). Both fractions were pure enough for use in the synthesis of HCV protease inhibitors: [α]D25+38.2° (c 1.0, MeOH).

Yield: 70.7 %

Procedure:
24.2 g (0.091 mol) of (S)-2-(2,4-dichloro-5-methoxyphenoxy)-propionic acid were suspended in a mixture of 150 ml of toluene and 0.5 ml of dimethylformamide and the suspension was stirred under nitrogen. 15.0 ml (0.17 mol) of oxalyl chloride were added, with vigorous evolution of gas occurring. The mixture was stirred for 1 hour to give a homogeneous solution. The solvents were removed by evaporation, the residue was taken up in 100 ml of diethyl ether and the solution was added to a solution of 24.6 g (0.090 mol) of 1-(5-amino-2,5-dideoxy-2-fluoro-β-D-arabinofuranosyl)-5-ethyluracil in 290 ml of 0.31M sodium hydroxide solution. The heterogeneous mixture was shaken vigorously for 10 minutes to give a white precipitate which was filtered off and washed firstly with water and then with diethyl ether. The crude product was recrystallized from hot methanol to give 33.1 g (69.7%) of 1-[5-[2(S)-(2,4-dichloro-5-methoxyphenoxy)propionamido]-2,5-dideoxy-2-fluoro-β-D-arabinofuranosyl]-5-ethyluracil as a white crystalline solid, m.p. 195°-196° C.
