Procedure: A mixture of 4-chloro-7-(3,5-dimethyl-4-isoxazolyl)-6-(methyloxy)-3-quinolinecarboxamide (for a preparation see Intermediate 56, 200 mg,) and [(5-methyl-2-furanyl)methyl]amine (200 mg) in 1,4-dioxane was heated to reflux overnight. The reaction mixture was evaporated to dryness and the residue was taken-up in DCM and washed with a saturated solution of sodium hydrogen carbonate. The organic was dried over Na2SO4, filtered and concentrated. The residue was purified by chromatography to give 7-(3,5-dimethyl-4-isoxazolyl)-4-{[(5-methyl-2-furanyl)methyl]amino}-6-(methyloxy)-3-quinolinecarboxamide (177 mg) as a beige powder. to reflux overnight The reaction mixture was evaporated to dryness washed with a saturated solution of sodium hydrogen carbonate The organic was dried over Na2SO4 filtered concentrated The residue was purified by chromatography

Procedure: Combine 7-chloro-3-(2,2,2-trifluoroacetyl)-6-trifluoromethanesulfonyloxy-2,3,4,5-tetrahydro-1H-benzo[d]azepine (100 mg, 0.24 mmol), 2-(di-tert-butylphosphino)-biphenyl (6.8 mg, 0.023 mmol), tris(dibenzylideneacetone)dipalladium (11 mg, 0.012 mmol) and potassium phosphate (70 mg, 0.33 mmol) in a pressure tube and degas. Dissolve the mixture in dry toluene (2 mL) and degas. Add a solution of 5-methylfurfurylamine (30 mg, 0.27 mmol) in toluene (1 mL) and degas. Stir at 90° C. for 24 h. Cool to ambient temperature, dilute with ethyl ether and filter through Celite®. Concentrate and purify by chromatography on silica gel eluting with hexane/EtOAc (20:1). Remove the solvent and add 7M ammonia in methanol (4 mL). Stir at ambient temperature for 24 h. Concentrate and purify by SCX chromatography to give the free base of the title compound. Use a method similar to the General Procedure 2-2 to obtain the title compound as a solid (56 mg, 66%).

Procedure: A mixture of 40 parts of 5-methyl-2-furanmethanamine, 46 parts of 1-chloro-2-nitrobenzene and 210 parts of N,N-diethylethanamine was stirred and refluxed for 2 days. The reaction mixture was evaporated, water was added and the product was extracted with dichloroethane. The extract was dried, filtered and evaporated. The residue was purified by filtration over silica gel using trichloromethane as eluent. The filtrate was evaporated, yielding 62 parts (89%) of 5-methyl-N-(2-nitrophenyl)-2-furanmethanamine as a residue (intermediate 2). refluxed for 2 days The reaction mixture was evaporated water was added the product was extracted with dichloroethane The extract was dried filtered evaporated The residue was purified by filtration over silica gel The filtrate was evaporated
