Yield:16926-73-1 1.3 g
Reaction Conditions:
with palladium on activated charcoal;hydrogen in N,N-dimethyl-formamide at 20; under 3750.38 Torr; for 24 h;Autoclave;
Steps:
2
To the autoclave were added 1.8 g of bis (4-nitrophenyl) terephthalate,30 ml of DMF and 0.01 g of Pd / C were placed and refluxed under a hydrogen gas pressure of 5 bar for 24 hours to obtain 1.3 g of a new diamine as an end product represented by the following formula (16).Thus, a diamine compound containing an ester group and a phenyl group could be prepared. The schematic preparation reaction of the diamine compound of Example 2 is shown in Reaction Scheme 2
