2,3-Diaminophenol Use and Manufacturing

1 l-(3-chlorophenyl)-6-hydroxy-3, 3-dimethyl-2, 3, 4, 5, 10, l 1-hexahydro- dibenzo, e] , 41diazepin- 1 -one (6).; Step l; A mixture of 2-amino-3-nitrophenol (10.0 g, 64.9 mmol), 10percent Pd/C in ethanol (150 mL), was hydrogenated at room temperature for 12 h. Then, the reaction mixture was degassed with nitrogen. The catalyst was removed by filtration and washed extensively with ethanol. The filtrate was evaporated to give 8.0 g (99percent) of the desired product as a black solid.Step 3. synthesis of 2, 3-diaminophenol (4). ; General procedure: To a solution of 4-amino-3-nitrophenol (28, 5.0 g, 32.44 mmol) was added cautiously Raney-Ni (1.0 g, wet weight) under N
