N-(2-methylpropyl)cyclopentanamine

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Following the general method as outlined in Example 20, starting from 6-chloro-pyrimidine-4-carboxylic acid (1H-indazol-5-yl)-amide (Intermediate 16) and cyclopentyl-isobutyl-amine (Intermediate 27), the title compound was obtained as a white solid in 78% yield.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Following the general method as outlined in Example 20, starting from 6-chloro-pyrimidine-4-carboxylic acid (2-methyl-4-sulfamoyl-phenyl)-amide (Intermediate 17) and cyclopentyl-isobutyl-amine (Intermediate 27), the title compound was obtained as a white solid in 80% yield.

Conditions: temp:70.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of cyclopentanone (10 g, 0.12 mol) and isobutyl amine (29.5 ml, 0.297 mol) was heated at 70° C. for 3 h under nitrogen. After cooling to 0° C., absolute ethanol (50 ml) was added to the reaction mixture, followed by sodium borohydride (6.59 g, 0.178 mol) in portions. The reaction mixture stirred at RT for 12 h, the solvent was removed under vacuum. The residue was taken up in MTBE and washed with water and brine. The organic layer was dried over Na2SO4, evaporated to dryness and the crude was purified by chromatography using silica gel (60-120 mesh), dichloromethane\methanol as eluent to afford of the titled compound as a yellow liquid. After cooling to 0° C. the solvent was removed under vacuum washed with water and brine The organic layer was dried over Na2SO4 evaporated to dryness the crude was purified by chromatography
