A mixture of benzyl(piperidin-4-ylmethyl)carbamate (7.77 g, 31.3 mmol, prepared according to Bose, D. Subhas et al., Tetrahedron Lett., 1990, 31, 6903) and 1,6-dioxaspiro[2.5]octane (4.29 g, 37.6 mmol, prepared according to Satyamurthy, Nagichettiar et al., Phosphorus Sulfur, 1984, 19, 113) in methanol (93 mL) was stirred at room temperature for 20 h.

Procedure:
The tricyclic nucleoside 6.7 was synthesized starting from 4-chloro-1H-pyrrolo[2,3-d]pyrimidine 2.1. The nucleobase 2.1 was treated with N-iodosuccinimide in THF at room temperature for 4 hr to provide 4-chloro-5-iodo-7H-pyrrolo[2,3-d]pyrimidine 6.1. Then 6.1 was converted to the corresponding sodium salt with sodium hydride in acetonitrile and reacted with bromo-sugar 2.4 ((i)Helv. Chim. Acta. 1995, 78, 486; (ii) WO 02/057287, 2002), to give nucleoside 6.2. which was directly converted to 4-amino-5-iodo-7-[3,5-bis-O-(2,4-dichlorophenylmethyl)-2-C-methyl-β-D-ribofuranosyl]-7H-pyrrolo[2,3-d]pyrimidine 6.3. A Stille coupling reaction between nucleoside 6.3 and Z-3-tributylstannylacrylate provided compound 6.4. The cyclization of compound 6.4 was accomplished by heating in DBU/dioxane overnight to afford the protected tricyclic nucleoside 6.5, which was then treated with boron trichloride in CH2Cl2 to produce nucleoside 6.6.

This mixture was stirred at 0° C. for 1 hour and at room temperature for 15 hours, after which it was poured into water and extracted with ethyl acetate-tetrahydrofuran (3:1). The ethyl acetate layer was washed successively with 1N HCl , water, a saturated sodium hydrogencarbonate solution, water and brine, and dried (MgSO4), after which the solvent was distilled off. The residual solid was collected by filtration, followed by recrystallization from ethanol-hexane to yield (2R,4S)-(−)-N-[4-(dimethoxyphosphorylmethyl)phenyl]-1,2,4,5-tetrahydro-4-methyl-7,8-methylenedioxy-5-oxo-3-benzothiepin-2-carboxamide (0.92 g, 64%). Colorless needles. Melting point 198-199° C. Optical rotation [α]D (23° C.) −198.8° (c=0.50, CHCl3).

Procedure:
4-Chloro-5-methyl-benzene-1,2-diamine (5.06 g; 32.3 mmoles) and 3,3,3-trifluoro-2-hydroxy-propionic acid (7.11 g; 49.4 mmoles) were suspended in 6N HCl (12 mL; 72 mmoles) under a nitrogen atmosphere.

The reaction was diluted with water (100 mL) and with ethyl acetate (100 mL), then sodium bicarbonate (9.12 g; 109 mmoles) was added slowly and in portions to quench the reaction. The aqueous layer was separated and extracted with ethyl acetate (3×40 mL). The extracts were combined, washed with water (30 mL) and brine (30 mL), then dried over Na2SO4. The filtrate was concentrated in vacuo to yield a crude brown solid which was then purified by column chromatography (SiO2; 30% ethyl acetate/CH2Cl2) to yield the title compound as a purple/brown solid.
