Procedure:
4-(5-Carboxy-naphthalene-1-sulfonylamino)-piperidine-1-carboxylic acid tert-butyl ester 46 (246 mg, 0.57 mmol) was dissolved in dichloromethane (5 mL). O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU) (323 mg, 0.85 mmol) was added followed by diisopropylethyl amine (214 mg, 0.29 mL, 1.66 mmol) and 2-methyl-cyclohexylamine (71 mg, 0.63 mmol). The reaction was stirred overnight at room temperature. The reaction mixture was charged to a flash column. Elution with 99:1 dichloromethane:methanol afforded 47 (380 mg) as a white foam that was contaminated with tetramethylurea, but suitable for use without further purification. 1H NMR (300 MHz, CDCl3) (1:1 mixture of diastereomers) δ 8.70 (m, 1H), 8.55 (d, 1H), 8.33 (d. 1H), 7.64 (m, 3H), 5.81 (d, 0.5H), 5.55 (d, 0.5H), 4.66 (d, 1H), 3.82 (m, 2H), 3.00 (m, 2H), 2.70 (m, 2H), 1.80 (m, 2H), 1.40 (s, 9H), 1.23 (m, 5H), 1.11 (d, 1.5H), 0.97 (d, 1.5H); LC/MS m/z 530 (M+H)+.

Procedure:
All reactions reported in this invention were carried in oven-dried three-necked, round-bottomed flasks equipped with a Teflon-coated magnetic stirring bar. The reaction flask was purged with nitrogen, and during the entire operation, the reaction was under nitrogen. To a stirred solution of cyclopropanamine (0.615 g, 10.78 mmol) in 25 mL of dried THF, triethylamine (1.20 g, 11.90 mmol) was added in one portion. After the reaction had been cooled to about 0° C., methyl 10-chloro-10-oxodecanoate (2.53 g, 10.78 mmol) in 5 mL of THF was added dropwise via an addition funnel. After the addition, the reaction was allowed to warm to ambient temperature and stirred overnight. The reaction mixture was subjected to roto-vap distillation to remove the majority of solvent, and the residue was poured with stirring into a mixture of ice-water containing 10 mL of HCl aqueous 2N solution (20 mmol) leading to the immediate precipitation of a white solid. Stirring was continued for an additional 30 min, and then the precipitation was filtered off with suction through a sintered glass funnel. The collected solid was washed with two 50-mL portions of water. The NMR analysis of a dried sample of the material confirmed the structure of the desired ester. The GC retention time of the ester is 12.79 min. The ester was saponified with 20 mL of NaOH aqueous 2N solution (40 mmol) at room temperature overnight. Ice was added to the reaction and acidification with a 30 mL of HCl aqueous 2N solution (60 mmol) led to the immediate precipitation of a white solid. Stirring was continued for an additional 30 min, and then the precipitation was filtered off with suction through a sintered glass funnel. The collected solid was successively washed with three 50-mL portions of water, and two 25-mL portions of hexane. The collected solid was dried in vacuo for two days at ambient temperature to afford 1.81 g (70%) of 10-(cyclopropylamino)-10-oxodecanoic acid as a white solid.

Procedure:
To 200 ml of acetonitrile were added 5.4 g (23.5 mmol) of O-isopropyl 3-isopentylbenzohydroxamic acid, 9.9 g (37.8 mmol) of triphenylphosphine, and 11.6 g (75.3 mmol) of carbon tetrachloride. The mixture was refluxed for 1 hour. The refluxed mixture was allowed to sit and cool naturally, and the solvent in the mixture was removed under reduced pressure. The residue was purified by column chromatography, thus obtaining the desired product of 5.1 g (yield: 88%).

Procedure:
Diketene (0.7 ml, 9.1 mmol) was added dropwise to a stirred solution of 5a (1.0 g, 4.3 mmol) in 7 ml of methanesulfonic acid. The resultant solution was heated at 70° C. for 5 min and cooled. Methanol (20 ml) was added and the reaction was heated to boiling; this treatment esterified small amount of free acid formed during the cyclization step. Methanol was evaporated and water was added to precipitate the product. The crude material was chromatographed on silica eluting with ethyl acetate. Concentration of the pure product fractions and drying under vacuum afforded 0.82 g (64%) of the desired product as a pale yellow solid. 1H NMR (DMSO-d6): δ 10.45 (s, 1H), 7.50 (s, 1H), 6.24 (s, 1H), 3.59 (s, 3H), 2.93 (t, J=7.5 Hz, 2H), 2.62 (t, J=7.5 Hz, 2H), 2.38 (s, 3H).

Upon completion of addition, the reaction mixture was maintained in the ice-water bath for about one hour. After this time the reaction mixture was poured into about 600 mL of water. The mixture was then extracted with two 200 mL portions of diethyl ether. The combined extracts were washed with two 100 mL portions of an aqueous 10% lithium chloride solution. The organic layer was dried with magnesium sulfate and filtered. The filtrate was concentrated under reduced pressure, yielding 12.3 grams of 7-amino-4-bromo-2,3-dihydro-2,2-dimethylbenzofuran. The NMR spectrum was consistent with the proposed structure.

Procedure:
To a of mixture of POCl3 (30 mL) and triethylamine (50 mL) at 0° C. was added 4-oxo-3,5,6,8-tetrahydro-4H-9-thia-1,3,7-triaza-fluorene-7-carboxylic acid tert-butyl ester (10.0 g).

Procedure:
A solution of 0.25 mL of acetyl chloride in 3 mL of dry dichloromethane was added slowly under nitrogen at 0° C. with stirring to a solution of 1.5 g (3.4 mmol) of 1-(1,1-dimethylethyl)-5-hydroxy-4-(2-methyl-4-methylsulfonyl-3-(4-methoxyphenyl)benzoyl)pyrazole and 0.52 mL of triethylamine in about 20 mL of dry dichloromethane. The mixture was allowed to warm to ambient temperature and stir for 2 hours and was then diluted with dichloromethane. The resulting solution was extracted with saturated aqueous sodium bicarbonate solution and with water, dried over magnesium sulfate, filtered, and concentrated by evaporation under reduced pressure. The residual yellow oil was chromatographed on silica gel eluting with a 50:50 mixture of ethyl acetate and hexane. The product fractions were combined and concentrated by evaporation under reduced pressure to obtain 1.03 g (62 percent of theory) of the title compound as a white powder melting at 160-163° C.

Procedure:
tert-Butyl [4-(7-benzyloxy-3-nitroquinolin-4-ylamino)butyl]carbamate (39.92 g, 85.57 mmol) was dissolved in toluene (1700 mL) and added to a Parr vessel charged with 5% platinum on carbon (3.9 g) and a small volume of toluene. The vessel was placed under hydrogen pressure (50 psi, 3.4×105 Pa). The hydrogen was replaced three times, and the reaction was shaken overnight. The reaction mixture was filtered through a layer of CELITE filter aid, and the filter cake was washed with ethanol (700 mL). The filtrate was concentrated under reduced pressure to provide 28.62 g of tert-butyl {4-[3-amino-7-(benzyloxy)quinolin-4-ylamino]butyl}carbamate as a brown solid.
