実験手順
To a solution of (1-(4-azidomethyl-thiazol-2-yl)-3-(2-cyclopentanecarbonyl-4-methylphenyl)-urea) (7.7 g, 20 mmol) in EtOH (100 mL) was added catalytic amount of palladium on charcoal (200 mg) and the reaction mixture was hydrogenated (1 atmos) for 3-4 hours to give 1-(4-aminomethyl-thiazol-2-yl)-3-(2-cyclopentanecarbonyl-4-methyl-phenyl)-urea. This crude product was then purified by flash column chromatography with DCM:EtOAc (80:20 to 50:50) as eluent to give the desired amine (5.7 g, 80%).
