Procedure:
Bromoacetaldehyde diethyl acetal (12.2 mL, 81.4 mmol) and a solution of 48% HBr (0.94 mL) are heated at reflux for 1.5 hours, then poured into a suspension of NaHCO3 (1.92 g) in propan-2-ol (31.3 mL). The resulting solid is filtered off and 3-amino-5-methyl-pyrazin-2-ol (3.13 g, 25.0 mmol) is added. The solution is refluxed for 2 hours then left to stand overnight and the solid formed washed with IPA and ether. The solid is added to a solution of DCM (60 mL) and NaHCO3 sat. (30 mL), the two layers are separated and the aqueous phase is extracted with DCM. The combined organic layers are dried with MgSO4 anh., filtered and evaporated to give a brown solid product. The aqueous phase is again extracted with a CHCl3/IPA 9/1, dried with MgSO4 anh., filtered and concentrated to give a brown solid product. The IPA and Ether used previously for washing the solid are combined, evaporated and submitted to the same process described previously to give a brown solid quite impurified from the DCM extraction and a brown solid with the CHCl3/IPA of similar purity to the one obtained beforehand. The products resulting from the first DCM extraction and the two CHCl3/IPA extraction are combined and washed with cold MeOH to give 5-Methyl-imidazo[1,2-a]pyrazin-8-ol as a pale yellow solid (1.32 g) that is submitted into the next step without further purification.

Procedure:
Potassium carbonate (2.85 g, 20.6 mmol) and 2-chloro-5-chloromethylpyridine (3.33 g, 20.6 mmol) were added to the DMF solution (125 ml) of 2-butoxyadenine (2.60 g, 12.5 mmol) obtained in Reference Example 1. The resultant was stirred while heating at 80° C. for 2.5 hours. The reaction solution was concentrated under reduced pressure, water (100 ml) was added thereto, and the resultant was neutralized with 1N hydrochloric acid. The precipitated solid was collected by filtration. The resulting solid was dissolved in methylene chloride (100 ml), hexane (150 ml) was added under ice cooling, and the precipitated crystal was collected by filtration. Thus, 2-butoxy-9-(6-chloro-3-pyridylmethyl)adenine was obtained (yield: 3.12 g). Bromine (1.92 ml, 37.5 mmol) was added to an acetic acid suspension (186 ml) comprising sodium acetate (3.05 g, 37.2 mmol) and 2-butoxy-9-(6-chloro-3-pyridylmethyl)adenine (3.1 g, 9.31 mmol) at room temperature, and the resultant was allowed to react for 4 hours. The reaction solution was removed by distillation under reduced pressure, water (200 ml) was added to the residue, and the resultant was neutralized with 5N sodium hydroxide under ice cooling. The precipitated crystal was collected by filtration, and crude crystal was recrystalized with the aid of methanol. The resultant was dried under reduced pressure at 40° C. for 15 hours. Thus, 2.38 g of the title compound was obtained as a white powdery crystal (yield: 62%).

Procedure:
The crude 1,1-dimethylethyl (3S)-3-[(3-chloro-4-cyanophenyl)amino]-4-{ethyl[(2-nitrophenyl)sulfonyl]amino}butanoate from the previous step (16.2 mmol), phenyl hydrosulfide (1.0 equiv., 1.78 g, 16.2 mmol), and K2CO3 (325 mesh, 3 equiv., 6.71 g, 48.6 mmol) in DMF (60 mL) were stirred at room temperature for 90 min. The reaction mixture was diluted with H2O (200 mL) and extracted with Et2O (3×). The organic extracts were washed with H2O, and 10% aq. Na2CO3, dried, and concentrated to give the titled product which was contaminated with the 2-nitrophenyl phenyl sulfide by-product. This contaminated product was used directly in the next step.

Procedure:
Sodium hydride (16 g) was suspended in tetrahydrofuran (100 ml) and a solution of N-acetylpyrrolidone (25 g) and o-anisaldehyde (26.8 g) in tetrahydrofuran (100 ml) was added dropwise under ice-cooling. After completion of the reaction, the reaction mixture was poured into water. The mixture was acidified with hydrochloric acid and extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate. After filtration, the solvent was evaporated under reduced pressure to give oily 3-(2′-methoxybenzylidene)-2-pyrrolidone (4.7 g). The oil was dissolved in methylene chloride (60 ml). By demethylation using boron tribromide under ice-cooling, 3-(2′-hydroxybenzylidene)-2-pyrrolidone (4.0 g) was obtained as yellow crystals. To the crystals (1.5 g) were added dimethylformamide (50 ml) and potassium carbonate (2.2 g). (S)-Glycidyl nosylate (2.3 g) was added and the mixture was stirred at room temperature for 2 days. The reaction mixture was concentrated under reduced pressure and water was added. The mixture was extracted with chloroform. The organic layer was dried over anhydrous sodium sulfate to give an oily compound (1.8 g). By the reaction of the oil (0.5 g) and 4-(5,6,7,8-tetrahydronaphthalen-2-yl)piperidine (0.5 g) in methanol in the same manner as in Example 307, the title compound (0.4 g) was obtained, melting point 157–159° C.

Procedure:
Ethyl 3-(2-aminothiazol-5-yl)oxybenzoate (Preparation 20; 2.0 g, 7,575 mmol) in 20 mL of dry THF was added slowly to stirring suspension of lithium aluminium hydride (0.287 g, 7.575 mmol) in 20 mL of dry THF in inert atmosphere and at 0° C. After complete addition the reaction was allowed to stir at room temperature for 3 hrs. TLC showed complete consumption of ethyl 3-(2-aminothiazol-5-yl)oxybenzoate. To the reaction mixture saturated NH4Cl solution was added and the layers were separated. The aqueous layer was extracted with ethyl acetate. The combined organic layer was washed with brine and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure to get the crude product which was taken as it was for next reaction without purification (1.74 g).
