Abstract
P hydroxy benzaldehyde reacts with bromine to form 3,5 bromo 4 hydroxy benzaldehyde,then fwthes reaction occurs with sodium methylate to obtain 3,5 methoxy 4 hydroxy benzaldehyde in the solution of DMF and employing cuprous chloride as catalyst.In the end,this compound is methylafed by bimethyl sulphade to synthesize 3,4,5 trimethoxy benzaldehyde at pH 10.
