Reaction Steps

N-(4-Cyano-2-nitrophenyl)glycine tert-butyl ester (17.337 g) was hydrogenated using 7.5% palladium carbon (1.73 g) in tetrahydrofuran (173 ml) at atmospheric pressure for 2 hours and by adding 7.5% palladium carbon (3.84 g) for one more hour. After completion of the reaction, the reaction mixture was filtered through celite and the solvent was evaporated. The obtained residue was washed with diisopropyl ether, collected by filtration and dried under reduced pressure to give the title compound (8.324 g).
