A 500 ml three neck round bottomed flask equipped with a stir bar, addition funnel, thermocouple, nitrogen inlet/outlet and cooling bath was charged with 11 g (99.9 mmol) of (S)-3-Phenyl-2-[(pyrazine-2-carbonyl)-amino]-propionic acid, 15.5.0 g (40.6 mmol) of O-(7-azabenzotriazol-1-yl)-N,N,N′N′-tetramethyluronium hexafluorophosphate (HATU), 12.2 g (40.6 mmol) of (1R)-1-[(3aS,4S,6S,7aR)-hexahydro-3a,5,5-trimethyl-4,6-methano-1,3,2-benzodioxaborol-2-yl]-3-methylbutylamine hydrochloride salt (87:13 mixture of isobutyl diastereomers (R:S)) and 165 mL of N,N-dimethylformamide (DMF). The pale yellow reaction solution was cooled to −35° C. where 12.6 g (17 mL, 97.3 mmol) of N,N-di-isopropyl ethyl amine was added dropwise over six minutes at −34° C. to −35° C. The resulting solution was then stirred overnight at −40 to −11° C. The reaction mixture was quenched onto 600 ml of a 1:1 cold water/ethyl acetate mixture. After transferring into a separatory funnel the layers were separated. The organic phase was then washed successively with 10% aqueous sodium hydrogen phosphate (1×200 mL), 8% aqueous sodium bicarbonate (2×200 mL) and saturated sodium chloride (1×200 mL). The product solution was dried over magnesium sulfate then filtered. The filtrate was evaporated to dryness in vacuo to give 19.57 g (37 7 mmol, 93%) of the title compound as a light brown foam with an HPLC purity of 92 A %. 1H NMR (d6-DMSO, 400 MHz) δ 9.15 (d, 1H, J=1.44 Hz), 8.87 (d, 1H, J=2.48 Hz), 8.7 (m, 3H), 7.25 (m, 4H), 7.18 (m, 1H), 4.89 (q, 1H, J=6.88, 15.4 Hz), 4.13 (dd, 1H, J=1.8, 8.56 Hz), 3.15 (d, 2H, J=6.88 Hz), 2.7 (m, b, 1H), 2.22 (m, b, 1H), 2.05 (m, b, 1H), 1.87 (t, 1H, J=5.40 Hz), 1.81 (s, b, 1H), 1.67 (d, b, 1H), 1.52 (m, b, 1H), 1.13-1.33 (m, 9H), 0.83 (dd, 6H, J=2.48, 6.56 Hz), 0.80 (s, 3H).

Procedure:
4-[(6,7-Dimethoxy-4-quinolyl)oxy]-2,3-dimethylaniline (86 mg) was added to toluene/triethylamine=10/1 (9 ml), and the mixture was heated under reflux to prepare a solution. A solution of triphosgene (117 mg) in methylene chloride was then added to the solution, and the mixture was heated under reflux for 15 min. Subsequently, 4-fluoro-α-methylbenzyl alcohol (55 mg) was added thereto, and the mixture was further stirred with heating under reflux for 2 hr. After the completion of the reaction, the reaction solution was allowed to cool to room temperature before distilled water was added thereto. The mixture was subjected to separatory extraction with chloroform, followed by washing with a 1 N aqueous hydrochloric acid solution and saturated brine. The washed solution was dried over sodium sulfate and was concentrated. The residue was purified on a column using chloroform/methanol to give the title compound (94 mg, yield 72%).

Procedure:
To a solution of 100 mg (0.26 mmol) of 4-anilino-5-(2,4-dimethoxy-anilino)-phthalimide in 8 ml of chloroform, a solution of 120 μl (1.24 mmol) boron tribromide is added dropwise at RT. The reaction mixture is stirred for 5 hours at RT, is then quenched with 5 ml of water and the phases are separated. The water phase is extracted three times with ethyl acetate. The organic phases are combined and washed twice with water, dried over magnesium sulfate and concentrated by evaporation. Excluding light, the evaporation residue is chromatographed with ethylacetate/hexane 2:1 on a silica gel column (precoated with 0.1 g of sodium ascorbate per g silica gel) that is cooled with ice-water (double jacket), the product fractions are combined and concentrated by evaporation. Recrystallization from ethyl acetate/dichloromethane/hexane yields the title compound in the form of yellow crystals, m.p. 155° C. (decomp.), FAB-MS: 362 [M+ +H].

Procedure:
To a solution of benzyl alcohol (1 mL) and triethylamine (2.69 mL) in dichloromethane (15 mL) was added 4-bromobutyryl chloride (1.68 mL), and the mixture was stirred at room temperature for 2 hours. The reaction mixture was poured into 1 mol/L hydrochloric acid, and the resulting mixture was extracted with diethyl ether. The extract was washed with water, a saturated aqueous sodium hydrogen carbonate solution and brine successively, and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure, and the residue was purified by column chromatography on silica gel (eluent: n-hexane/ethyl acetate=8/1) to give benzyl 4-bromobutyrate (2.45 g). To a solution of 3-(2,3,4,6-tetra-O-pivaloyl-β-D-glucopyranosyloxy)-4-[2-(4-pivaloyloxyphenyl)ethyl]-1H-pyrazolo[3,4-b]pyridine (0.17 g) in acetone (3 mL) were added cesium carbonate (0.16 g), benzyl 4-bromobutyrate (0.1 g) and a catalytic amount of sodium iodide, and the mixture was stirred at room temperature for 2 days. The reaction mixture was purified by column chromatography on silica gel (eluent: n-hexane/ethyl acetate=10/1-3/1) to give 1-(3-benzyloxycarbonylpropyl)-3-(β-D-glucopyranosyloxy)-4-[2-(4-pivaloyloxyphenyl)ethyl]-1H-pyrazolo[3,4-b]pyridine (0.14 g). This material was dissolved in tetrahydrofuran (5 mL). To the solution was added 10% palladium-carbon powder (50 mg), and the mixture was stirred at room temperature under a hydrogen atmosphere for 3 hours. The insoluble material was removed by filtration, and the filtrate was concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (eluent: n-hexane/ethyl acetate=1/2-dichloromethane/methanol=15/1) to give the title compound (95 mg).
