Procedure:
In one synthesis method, depicted in FIG. 1a, the synthesis comprises reacting cytosine, BSA and SnCl4/acetonitrile with 1,2,3,5-tetra-O-benzoyl-2-C-methyl-β-D-ribofuranose (1) to form 4-amino-1-(3,4-dibenzoyloxy-5-benzoyloxymethyl-3-methyl-tetrahydro-furan-2-yl)-1H-pyrimidin-2-one (2; and reacting (2) with NaOMe/MeOH to provide 4-amino-1 (3,4-dihydroxy-5-hydroxymethyl-3-methyl-tetrahydro-furan-2-yl)-1H-pyrimidin-2-one (3), also known as 2-C-methyl-β-D-ribofuranose. The use of cytosine as a starting material rather than benzoyl-cytosine improves the “atom economy” of the process and simplifies purification at later steps.

Procedure:
To a solution of 4-bromo-1-trityl-1H-imidazole (103 mg, 0.24 mmol, 1.0 equiv) in tetrahydrofuran (1 mL) was added ethyl magnesium bromide (3M in diethylether, 0.094 mL, 0.28 mmol, 1.2 equiv) and the reaction was stirred for 90 min. ZnCl2 (38 mg, 0.28 mmol, 1.2 equiv) was then added and the solution stirred for an additional 90 min. Tetrakis (triphenylphosphine)palladium (2 mg, 0.024 mmol, 0.10 equiv) and 3-bromo-6-(6-methyl-[1,2,4]triazolo[4,3-b]pyridazin-3-ylmethyl)-quinoline (100 mg, 0.28 mmol, 1.2 equiv) were added and the solution heated at 70° C. for 18 hours. The solvent was removed in vacuo and the residue absorbed onto silica gel and purified by flash chromatography (SiO2, CH2Cl2:CH3OH 100:0-80:20 to return 6-(6-methyl-[1,2,4]triazolo[4,3-b]pyridazin-3-ylmethyl)-3-(3-trityl-3H-imidazol-4-yl)-quinoline. The trityl group was removed by stirring the compound in methanolic hydrochloric acid (0.5 N) for 3 hours. The volatiles were removed in vacuo and the residue stirred in ethanol and collected via filtration and dried to return the title compound (5.6 mg, 8% yield). Analytical data presented in Table 2.
