Ammonia → 2-Amino-5-(4'-hydroxy-2',3'-dimethyl anilino)-1,4-benzoquinone

참여 물질

반응 단계

0.01 mole (1.39 g) of 3-amino-4-methoxy phenol is dissolved in 100 cc of water to which have been added 50 cc of acetone and 10 cc of ammonia (22° Be'). To this solution there are added 100 cc of H2O2 (20 volumes) and immediately thereafter, with good agitation, 0.01 mole (1.37 g) of 2,3-dimethyl-4-amino phenol in suspension in 100 cc of water. The resulting reaction mixture is agitated for three hours at which time it is filtered to recover the 2-amino-5-(4'-hydroxy-2',3'-dimethyl anilino)-1,4-benzoquinone which is first washed with water and then with acetone. It is dried for 8 hours under a vacuum with a boiling water bath and is chromatographically pure, melting at 320° C.
