Reaction Steps
0.160 g (1.500 mmol) of palladium on carbon (10%) and 15.19 ml (150 mmol) of cyclohexene are added to a solution of 4.82 g (15 mmol) of tert-butyl 4-(4-methylpiperazin-1-yl)-2-nitrobenzoate in 100 ml of ethanol. The reaction mixture is heated at a temperature of 80° C. for 8 hours. The reaction mixture is filtered and then rinsed with ethanol to yield 4.2 g (yield=96%) of tert-butyl 2-amino-4-(4-methylpiperazin-1-yl)benzoate in the form of a yellow solid.
