Yield:-
Reaction Conditions:
with hydrogen;acetic acid;5%-palladium/activated carbon under 15201 Torr; for 16 h;
Steps:
2.ii (ii) 2, 3-Diamino-6-chlorobenzonitrile
2-Amino-6-chloro-3-nitrobenzonitrile (8g) in acetic acid (100ML) was treated with 5% palladium on carbon (LG) and the mixture hydrogenated at 20 atmospheres for 16HRS. The catalyst was filtered off and the acetic acid removed in vacuo to give 2,3-diamino-6- chlorobenzonitrile. 1H NMR (D6-DMSO) : 8 6.63 (1H, dd), 6.55 (1H, dd), 5.73 (2H, broad s), 5.13 (2H, broad s).
