2-[[(4-chlorophenyl)sulfonyl]methyl]-1,4-difluorobenzene (Intermediate 1) (100 g, 0.33 mol) and N,N,N′,N′-tetramethyldiaminomethane (34.2 g, 0.50 mol) were dissolved in dimethyl formamide (1000 mL) at 60° C. Acetic anhydride (68.3 g, 1.00 mol) was added slowly and the reaction mixture was aged for 5 hours. Water (1000 mL) was added dropwise and the resulting slurry was cooled to 5° C. The solids were filtered, and the cake washed sequentially with dimethyl formamide:water (40:60, 200 mL) and water (500 mL). Drying overnight in vacuo at 40° C. under a nitrogen stream furnished 2-[1-[(4-chlorophenyl)sulfonyl]ethenyl]-1,4-difluorobenzene (98 g, 95%). 1H NMR (CDCl3) 7.64-7.59 (2H, m), 7.43-7.39 (2H, m), 7.27-7.22 (1H, m), 7.08-6.88 (2H, m), 6.88 (1H, s) and 6.09 (1H, s). (ii) A solution of 2-[1-[(4-chlorophenyl)sulfonyl]ethenyl]-1,4-difluorobenzene (100 g, 0.32 mol) in xylenes (500 ml) was azeotropically distilled at 38° C., 20 mmHg, until 300 mL solvent had been removed. 2-Trimethylsilyloxybutadiene (90.4 g, 0.64 mol) was then added under a nitrogen atmosphere and the mixture heated to 130° C. After the reaction was completed, the mixture was distilled in vacuo to remove residual diene, whilst maintaining a constant volume by the addition of xylenes (400 mL). The mixture was cooled to 50° C. and THF (500 mL) and 3M HCl (424 mL, 1.27 mol) were added. After the hydrolysis was complete, the layers were separated. The organic layer was washed with water (300 mL) and then concentrated by atmospheric distillation until 350 mL of solvent had been removed. The solution was allowed to cool until crystallisation started, heptane (600 mL) was added and the resulting mixture cooled to ambient. The solids were filtered and washed sequentially with heptane:xylenes (3:1, 200 ml) and then heptane (200 ml). Drying overnight in vacuo at 40° C. furnished 4-[(4-chlorophenyl)sulfonyl]-4-(2,5-difluorophenyl)cyclohexanone (110 g, 90% yield). 1H NMR CDCl3— as for the product obtained via Method (a).

Procedure:
2'-O-Propylguanosine (3.6 gm) in pyridine (50 ml) was cooled in an ice bath and trimethylsilyl chloride (8.4 ml, 6 eq.) was added. The reaction mixture was stirred for 30 min and isobutyryl chloride (5.8 ml, 5 eq.) was added. The solution was stirred for 4 hours during which it was allowed to warm to room temperature. The solution was cooled, H2O added (10 ml) and the solution was stirred for an additional 30 mins. Concentrated NH4OH (10 ml) was added and the solution evaporated in vacuo. The residue was purified by silica gel chromatography using 10% MeOH/CH2Cl2 to elute the product. Product-containing fractions were evaporated to yield 2.5 g of product as a foam.
