23% | With zinc(II) cyanide;tetrakis(triphenylphosphine) palladium(0); In DMF (N,N-dimethyl-formamide); at 120℃; for 96h; | A solution of 5-chloro-2-nitro-aniline (6.902g, 40 mmol), Zn(CN)2 (2.818g, 24 mmol), and Pd(PPh3)4 (2.31 lg, 2 mmol) in DMF (40 mL) was heated to 120oC for 4 days. Cooled to room temperature. Partitioned between ethyl acetate and water. The organic layer was washed with brine, dried (MgSO4), filtered, and concentrated under vacuum. The residue was purified by flash column chromatography on silica gel with 4:1 hexanes/ethyl acetate to provide 1.49g (23%) of 3-amino-4-nitro-benzonitrile. |

83% | With hydrogenchloride; In water; for 48h;Heating / reflux; | A mixture of <strong>[99512-10-4]3-amino-4-nitro-benzonitrile</strong> (1.2g, 7.36 mmol), concentrated HC1 (50 mL), and water (100 mL) was heated to reflux for 2 days. Cooled to room temperature and collected orange solid by filtration. Washed solid with water until wash was neutral, to provide 1.11 g (83%) of 3-amino-4-nitro-benzoic acid. |

63% | Step 1: 3-Amino-4-nitrobenzonitrile (274) [0431] A suspension of bromoarene 2 (801mg; 3.7 MMOL) and zinc cyanide (570mg; 4. 85MMOL ; 1. 3eq. ) in degassed DIMETHYLFORMAMIDE (15 mL) was stirred at room temperature under nitrogen in the dark for 45 min and then treated with tetrakis (TRIPHENYLPHOSPHINE) PALLADIUM (O) (310mg, 1. 6MMOL). The mixture was stirred at 90C for 18h; filtered through a celite pad, concentrated under reduced pressure and purified by flash chromatography on silica gel, eluent EtOAc-hexane (1 : 1) to afford the title compound 274 (380 mg, 63% YIELD). H NMR: (400.2 MHz, CDCI3) 8 (ppm): 8.22 (d, J=8.6 Hz; 1H); 7.19 (d, J=1.8 Hz; 1H) ; 6.95 (dd, J=1.8, 8.6 Hz; 1H) ; 6.27 (bs; 2H). MS: CALC : 163.1 ; found: 164.1 (M+H) |

70% | With hydrogen;palladium-carbon; In ethanol; | EXAMPLE 101 3,4-diaminobenzonitrile 3-Amino-4-nitrobenzonitrile (20.00 g, 0.042 mol) was hydrogenated under 50 psi of hydrogen gas in 250 mL of anhydrous ethanol with 1.00 g of 10% Pd/C for 5 hours. The mixture was then filtered through a pad of celite and the filtrate concentrated. Trituration of the resulting solid with diethyl ether afforded 11.40 g of the desired product as a tan solid (70%). 1H NMR (CD3OD): delta6.88 (m, 2H), 6.65 (d, 2H, J=8.53 Hz). |
