Step - (ii): Synthesis of 3-(4-methylpiperazin-1-yl)aniline: A methanolic solution of 1-methyl-4-(3-nitrophenyl)piperazine (15 g, 78.5 mmol) was mixed with a methanolic solution of 10% Pd/C (3 g) under stirring. The reaction was carried out under inert atmosphere with slow stirring and under hydrogen atmosphere for 4 hours at room temperature. After completion of the reaction, the reaction mixture was filtered through a diatomaceous earth pad. The filtrate was concentrated to afford the target product 3-(4-methylpiperazin-1-yl)aniline (11 g, 87%) as a light yellow solid. Mass spectrum (electrospray ionization) m/z: 192 (M + 1).
